GS-R400 Family
20W TO 140W STEP-DOWN
SWITCHING REGULATOR FAMILY
FEATURES
MTBF in excess of 200,000 hours
4A max output current
46V max input voltage
4V max drop-out voltage

DESCRIPTION
The GS-R400 series is a versatile family of high
current, high voltage step-down switching voltage
regulators.
The integral heatsink allows a large power handling
capability and it provides also an effective shielding
to minimize EMI.

Note: The line regulation is measured at Iout=1A
The load regulation is measured at Vin=Vo+8V and Iout=1 to 3A
For VO 36V and Io = 4A an external heatsink or forced ventilation are required.
