With typical rise and fall times of 20 ns and 18 ns respectively into a specified load, the switching transition losses stay low enough for power supplies switching in the 100-500 kHz range. The 4.5V to 20V supply range covers both 5V-logic and standard 12V gate drive rails used in telecom bricks and industrial DC-DC converters. Logic thresholds of 0.8V (VIL) and 2.4V (VIH) mean a 3.3V or 5V PWM controller can drive the input directly without a level shifter. ## Low-side topology and dual independent channels Configured as a low-side driver, the MIC4128YME drives the source terminal of an N-channel MOSFET to ground — suited for buck converters, forward converters, and synchronous rectifier stages where the FET source is referenced to the return rail. The two channels are independent with separate inverting and non-inverting inputs, so one channel can drive the main switch while the other drives an active clamp or synchronous rectifier.","metaTitle":"MIC4128YME Low-Side Gate Driver, 1.5A Peak, 8-SOIC-EP","metaDescription":"Active-production MIC4128YME from Microchip.
