The Microchip fixed-frequency, current-mode PWM controller built using BiCMOS technology. It’s designed to drive large MOSFETs efficiently, making it ideal for DC/DC converters and switched-mode power supplies. With fast switching speeds, rail-to-rail output capability, and ultra-low startup and operating currents, it supports multiple topologies like buck, boost, flyback, and forward converters. Its compact design and built-in protection features make it a solid choice for high-efficiency, space-constrained systems.
