Product Overview

These DC-DC converter modules use advanced power

processing, control and packaging technologies to provide

the performance, flexibility, reliability and cost effectiveness

of a mature power component. High frequency Active Clamp

switching provides high power density with low noise and

high efficiency.

 

Product’s Introduction

The YN100 series is an independently regulated single output converter that uses the industry standard quarter brick package size. The very high efficiency is a result of ENARGY CORP patented topology that uses synchronous rectification and an innovative construction design to minimize heat dissipation and allow extremely high power densities. The power dissipated by the converter is so low that a heat sink is not required, which saves cost, weight, height, and application effort. All of the power and control components are mounted to the multi-layer PCB substrate with highyield surface mount technology, resulting in a more reliable product.

6. Pin Function Description

 

6.1 Enable (ON/OFF) Control (Pin 2):

The Enable pin allows the power module to be switched on and off electronically. The Enable (On/Off) function is

useful for conserving battery power, for pulsed power application or for power up sequencing.

The Enable pin is referenced to the -Vin. It is pulled up internally, so no external voltage source is required. An open

collector (or open drain) switch is recommended for the control of the Enable pin.

When using the Enable pin, make sure that the reference is really the -Vin pin, not ahead of EMI filtering or

remotely from the unit. Optically coupling the control signal and locating the opto coupler directly at the module will

avoid any of these problems. If the Enable pin is not used, it can be left floating (positive logic) or connected to the -Vin

pin (negative logic).Figure A details five possible circuits for driving the ON/OFF pin. Figure B is a detailed look of

the internal ON/OFF circuitry.

Figure A: Various circuits for driving the ON/OFF pin.

Figure B: Internal ON/OFF pin circuitry

 

6.2 Remote Sensing (Pins 7 and 5):

 Remote sensing allows the converter to sense the

output voltage directly at the point of load and thus

automatically compensates the load conductor distribution &

contact losses (Figure C). There is one sense lead for each

output terminal, designated +Sense and -Sense. These leads

carry very low current compared with the load leads.

Internally a resistor is connected between sense terminal and

power output terminal. If the remote sense is not used, the

sense leads needs to be shorted to their respective output

leads(Figure D).

Military Power Supply  single output

Figure C: Remote Sense Connection

Care has to be taken when making output

connections. If the output terminals should disconnect

before the sense lines, the full load current will flow down

the sense lines and damage the internal sensing resistors.

Be sure to always power down the converter before

making any output connections. The maximum

compensation voltage for line drop is up to 0.5V

Military Power Supply  single output

 

Figure D: Remote Sense is not Used.

6.3 Voltage Trim (Pin 6):

Output voltage can be adjusted up or down with an external resistor. There are positive trim logic and negative

trim logic available. For positive logic, the output voltage will increase when an external trimming resistor is connected

between the Trim and +Vout/+Sense pin. The output voltage will decrease when an external trimming resistor is

connected between Trim and -Vout/-Sense pin. A multi-turn 20Ký trim pot can also be used to adjust the output voltage

up or down.(Figure E & F)

7. Basic Operation and Features Application

 

7.1 Output Ripple & Noise Test:

The output ripple is composed of fundamental frequency ripple and high frequency switching noise spikes. The

fundamental switching frequency ripple (or basic ripple) is in the 100KHz to 1MHz range; the high frequency switching

noise spike (or switching noise) is in the 10 MHz to 50MHz range. The switching noise is normally specified with 20

MHz bandwidth to include all significant harmonics for the noise spikes.

The easiest way to measure the output ripple and noise is to use an oscilloscope probe tip and ground ring pressed

directly against the power converter output pins, as shown below. This makes the shortest possible connection across

the output terminals. The oscilloscope probe ground clip should never be used in the ripple and noise measurement. The

ground clip will not only act as an antenna and pickup the radiated high frequency energy, but it will introduce the

common-mode noise to the measurement as well.

The standard test setup for ripple & noise measurements is shown in Figure F. A probe socket (Tektronix, P.N.

131.0258-00) is used for the measurements to eliminate noise pickup associated with long ground clip of scope probes.

Figure G: Typical application circuit (negative logic unit, permanently enabled).

Application Circuits: Figure G below provides a typical circuit diagram which details the input filtering and voltage trimming.

 

7.3 Input Filtering

DC-DC converters, by nature, generate significant

levels of both conducted and radiated noise. There are two

types of conducted noise: common mode and differential

mode noise. The common mode noise is directly related to

the effective parasitic capacitance between the power

module input conductors and chassis ground. The

differential mode noise is across the input conductors. It is

recommended to have some level of EMI suppression to the

power module.

Conducted noise on the input power lines can occur as

either differential or common-mode noise currents. The

required standard for conducted emissions is EN55022

Class A (FCC Part15). (See Figure H)

7.4  Input Reflected Ripple Current

The converter is drawing current from input power source only when the input switch is on. This creates a pulsation current flow from the input source. The reflected ripple current is measured as a peak-to-peak current with a current probe over 0 to 20MHz bandwidth. Ripple current can be suppressed by an external Π (pi) filter as shown below. see Figure I.

Military Power Supply  single output

Figure I: Input Reflected Ripple Current

 

7.5 Protection Features

·Input Under-Voltage Lockout: The converter is designed to turn off when the input voltage is too low, helping avoid an input system instability problem, The lockout circuitry is a comparator with DC hysteresis. When the input voltage is rising, it must exceed the typical Turn-On Voltage Threshold value(listed on the specification page) before the converter will turn on. Once the converter is on, the input voltage must fall below the typical Turn-Off Voltage Threshold value before the converter will turn off.

·Output Current Limit: The maximum current limit remains constant as the output voltage drops. However, once the impedance of the short across the output is small enough to make the output voltage drop below the specified Output DC Current-Limit Shutdown Voltage, the converter into hiccup mode indefinite short circuit protection state until the short circuit condition is removed. This prevents excessive heating of the converter or the load board.

 ·Over-Temperature Shutdown: A temperature sensor on the converter senses the average temperature of the module. The thermal shutdown circuit is designed to turn the converter off when the temperature at the sensed location reaches the Over-Temperature Shutdown value. It will allow the converter to turn on again when the temperature of the sensed location falls by the amount of the Over-Temperature Shutdown Restart Hysteresis value.
