MIC38HC42YM Description

Short technical summary and product information.

The MIC38HC42YM from Microchip Technology is a fixed-frequency, current-mode PWM controller built on a high-performance, low-power BiCMOS process. This device offers a 1A peak current drive capability with fast 20ns output rise and 15ns fall times, making it suitable for applications requiring high efficiency.

 

Key electrical specifications include an operating voltage range of 9V to 20V and a switching frequency of up to 500kHz. The controller features ultralow startup current (50µA typical) and low operating current (4mA typical). It supports various topologies including Boost, Buck, Flyback, and Forward converters.

 

The MIC38HC42YM is housed in an 8-SOIC package and is designed for surface mount applications. It operates within a temperature range of -40°C to +85°C, exceeding standard UC284x specifications. Its pin-for-pin compatibility with UC384x series devices simplifies integration into existing designs.
