(270 kHz typical)
Remote Sense
The 700HBAW_1.6 series are half-brick DC/DC converters that provide
high efficiency single output. They can operate from 36VDC to 75VdD-
Cinput and 28V/25A output. The output can be trimmed from
(14VDC~33Vdc) of normal output voltage. The remote control option is
positive logic. The converter turns on when the REM pin is at logic high
and turns off when it at logic low, both are referenced to -Vin. The
converter is on when the REM pin is left open. The output voltage trim
option is positive. The output voltage will increase when the TRIM pin
connected to +S pin and decrease when it connected to -S pin. The
output voltage will increase when the TRIM pin connected to +S pin and
decrease when it connected to -S pin.
