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 XD series is an independently regulated single output converter that uses a industry nonstandard brick package. 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.

7. Function Specifications
7.1 Enable (ON/OFF) Control (Pin 1)

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.

7.2 Voltage Trim (Pin 6)
Output voltage can be adjusted up or down with an external resistor. The output voltage will increase when an
external trimming resistor is connected between the Trim and Com pin. The output voltage will decrease when an
external trimming resistor is connected between Trim and Vout(+) pin. (Figure C).

7.3 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.

Figure E: Input Filtering

 

8.2 Input Filtering

DC-DC converters, by nature, generate significant
levels of both conducted and radiated noises. The
conducted noises included common mode and differential
mode noises. 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 E)

 

9. Test Method
9.1 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.
