The MIC38HC44-1YM-TR is a fixed-frequency, current-mode Pulse Width Modulation (PWM) controller manufactured by Microchip Technology. This BiCMOS device offers a 1A drive current capability and is pin-compatible with bipolar 384x devices. It features a wide operating voltage range of 9V to 20V and a high switching frequency of up to 500kHz, with a duty cycle of 50% for this specific variant.
The controller is designed for high efficiency, with ultralow startup current (50µA typical) and low operating current (4mA typical). It includes features such as fast output rise and fall times (20ns and 15ns respectively), rail-to-rail output swing, and undervoltage lockout (UVLO) circuitry. The MIC38HC44-1YM-TR is housed in a 14-SOIC package, suitable for surface mount applications.
This PWM controller is well-suited for various power supply applications, including current-mode off-line switched-mode power supplies and DC-to-DC converters. Its design supports topologies such as boost, buck, flyback, and forward converters, making it a versatile component for power management designs.
