APPLICATION NOTES

POWER SUPPLIES

LOAD FAULT RESPONSE

The MSK families of DC-DC converters share load fault phi-

losophies. Load fault conditions include short-circuit and se-

vere overload conditions. The DAC2800S converter series re-

sponds to load faults by turning off all power conversion cir-

cuits for 250mS and then attempting to restart for 10mS (typi-

cal). The net "on" duty factor during a fault is very low result-

ing in low converter dissipation and immunity from overheating

at 125ꢀC. Current beyond rated can flow into the load at

startup time. This allows the converter to bring up capacitive

and other difficult load types more reliably than competing con-

verters.

The output voltage of the DAC2812S and DAC2815S may

be adjusted from 90% to 110% of nominal value by the use of

a 150KΩ potentiometer as shown. Adjustment beyond this

range is possible however certain characteristics of the con-

verter such as but not limited to input voltage range, efficiency,

ripple and temperature performance will change. Characteriza-

tion by the user is recommended in such applications.

Adjust/comp (pin 4) may be driven by external circuitry refer-

enced to pin 2 (-output) if desired. Grounding pin 4 causes

voltage to increase (25% typically) while driving pin 4 above

1.3V causes output voltage to decrease. Pin 4 may be driven

negative without damage, however the resultant increase in

converter output voltage should be considered. Pin 4 may be

driven through 10KΩ or more if connection of the comp func-

tion is also required.

The comp function of pin 4 allows load transient response to

be tailored to suit specific application requirements. This fea-

ture may be utilized by connecting a 10 or less nF capacitor

between pins 4 and 1.

Note: The DAC2812S and DAC2815S use pin 4 while the

DHC2803S and DHC2805S use pin 3.

SHUTDOWN PLUS

Pin 5 is used for remote shutdown, output fault detection,

and/or setting the input voltage point at which the converter

will turn on as shown in the typical application diagram. No

connection to pin 5 is necessary for normal operation of the

converter. Pin 5 is referenced to the pin 7 (-input).

Shutdown may be implemented by simply connecting pin 5

to an open collector logic output or switch rated at 2.5mA,

25Vdc or higher.

Input voltage turn on point is programmed with a single resis-

tor from pin 5 to 7. An input turn on/off hysteresis (typically

3.5% of Vin) will be observed. This should be considered when

making or verifying set point adjustment. The value of the

setpoint resistor may be determined by the following:

210·10³

( 10% accuracy at 25ꢀC)

ETO-9.5

Set point temperature coefficient is typically +400ppm/ꢀC.

Output fault monitoring is accomplished by observing pin 5

with a high impedance monitoring circuit. Pin 5 voltage drops

from over 10V to below 1V when a load fault causes the con-

verters fault protection circuitry to activate. It will remain low

for at least 100mS and return high. If the load fault is still

present pin 5 will return low and the cycle will repeat. A resis-

tor >400KΩ from pin 5 to 7 provides pull down for pin 5 if

there is no input setpoint programming resistor already in place.
