LQD40A48-3V3-1V8RAKJ Overview

isolated DC/DC converters 2out 1.8V/3.3V 20a 7-pin 1/4-brick

Quarter-Brick Series
Dual output
DC/DC CONVERTERS
High Current, High E ciency, Low Pro le
NEW Product
1
Two independent outputs
High full load e ciency
Wide ambient temperature range of -40 ºC to +85 ºC
Up to 100% load imbalance
Tracking, monotonic start-up
Starts into pre-biased outputs
Basic insulation system
Over-voltage and over-temperature protection
100 V, 100 ms input voltage transient response
Secondary side control, no optocouplers,
fast transient load response
Available RoHS compliant
These are new high e ciency, open-frame, isolated 40 A converters in an industry standard dual
quarter-brick footprint. These converters deliver high output current at low voltages, and excel-
lent useable power density for today’s high end applications. This series features an input volt-
age range of 36 Vdc to 75 Vdc and output voltages of 1.2 V/3.3 V, 1.5 V/3.3 V, 1.8 V/3.3 V 2.5
V/3.3 V, and 5 V/3.3 V. The output voltage on each model is adjustable from 90% to 110% of
the nominal value. Typical e ciencies are 90%. This series also has a remote ON/OFF capabili-
ty. Over-current and over-voltage protection features are included as standard. Designed to
meet inter national safety agency approvals, including EN60950-1 and UL/cUL60950, this series
reduces compliance costs and time to market.

Does anyone know if function parameters in KEIL C can have default values?
For example, #include xxxxx .... void F1(uchar a,b,c,d) { if(a==NULL) //Can it be written like this? .......... } main() { F1(,,3,4); //Or F1(NULL,NULL,3,4) Similar to the writing method in C++..... }...
