1 / 5 page GS-R400 Family 20W TO 140W STEP-DOWN SWITCHING REGULATOR FAMILY June 1994 1/5 FEATURES MTBF in excess of 200,000 hours 4A max output current 46V max input voltage 4V max drop-out voltage Soft start Remote logic inhibit/enable Remote output voltage sense Non-latching overload and short circuit protection Crow-bar output overvoltage protection 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.
