The MIC38HC43-1YN from Microchip Technology is a fixed-frequency, current-mode PWM controller designed for high efficiency in switched-mode power supplies. This BiCMOS device offers a 1A current drive capability with fast output rise and fall times, making it suitable for driving larger MOSFETs.
Key electrical specifications include an operating voltage range of 7.6V to 20V and an operating temperature range of -40°C to 85°C. It supports various topologies such as buck, boost, flyback, and forward converters. The controller features ultralow startup current (50µA typical) and low operating current (4mA typical).
This controller is available in a 14-pin DIP package, designed for surface mounting. Its features include rail-to-rail output capability and a trimmed 5V bandgap reference, contributing to increased efficiency, especially at lower supply voltages. The MIC38HC43-1YN is pin-for-pin compatible with UC3842/3/4/5(A) bipolar devices.
