The Microchip fixed-frequency, current-mode PWM controller designed for efficient DC/DC power conversion. Built using BiCMOS technology, it offers fast switching speeds, low startup and operating currents, and rail-to-rail output capability. It’s compatible with multiple topologies like forward, flyback, and boost converters, making it versatile for use in telecom, networking, and automotive power supplies. With features like under voltage lockout, trimmed oscillator discharge current, and a precision bandgap reference, it delivers reliable performance in compact systems.
