MIC38HC44YM Description

Short technical summary and product information.

The MIC38HC44YM is a fixed-frequency, current-mode PWM controller from Microchip Technology, built on a high-performance, low-power BiCMOS process. It offers 1A drive current capability and is pin-compatible with bipolar UC384x devices.

 

Key electrical specifications include an operating voltage range of 9V to 20V, a maximum frequency of 500kHz, and a duty cycle of 50%. It features fast output rise and fall times of 20ns and 15ns respectively, ultralow startup current of 50µA typical, and low operating current of 4mA typical. The device also includes a trimmed 5V bandgap reference and UVLO with hysteresis.

 

This controller is suitable for various power supply applications, including off-line switched-mode power supplies and DC-to-DC converters such as buck, boost, flyback, and forward converters. It is available in an 8-SOIC package suitable for surface mounting.
