Product Overview
The controller includes UVEN and OV inputs, a GATE output, TIMER timing functions, PG and FLT outputs, VREF, PROG, OUT, SENSE, and IMON functions. Electrical limits include -0.3 to 100 V absolute maximum ratings on VCC, SENSE, UVEN, OUT, GATE, PG, and FLT related pins where specified, while PROG, OV, TIMER, VREF, and IMON are limited to -0.3 to 6 V where specified.
For current control, the datasheet facts list 17 to 33 mV current-limit thresholds with power limiting under stated PROG and OUT conditions, and 45 to 55 mV without power limiting. It also provides ILIM = 50 mV / RSENSE for low FET VDS current limit. Monitoring is supported through IMON, with VIMON = 48 x (VCC - SENSE), 48 V/V typical gain, and 2.8 V typical maximum output voltage.
