The MIC38HC42-1YN from Microchip Technology is a fixed-frequency, current-mode PWM controller designed for high efficiency in switched-mode power supplies. This BiCMOS device features a 1A peak output drive current and operates at frequencies up to 500kHz.
Key electrical characteristics include an operating voltage range of 9V to 20V and a low operating current of 4mA typical. The controller boasts fast output rise and fall times of 20ns and 15ns respectively, along with ultralow startup current of 50µA typical. It supports various topologies including boost, buck, flyback, and forward converters.
Designed for demanding environments, the MIC38HC42-1YN operates within a temperature range of -40°C to 150°C. It is supplied in a 14-DIP (0.300", 7.62mm) through-hole package, suitable for applications requiring robust power management solutions.
This controller is pin-compatible with industry-standard bipolar devices, offering an upgrade path for existing designs. Its features make it ideal for off-line and DC-to-DC converters where high performance and efficiency are critical.
