MIC38HC43YM-TR Description

Short technical summary and product information.

The MIC38HC43YM-TR from Microchip Technology is a fixed-frequency, current-mode Pulse Width Modulation (PWM) controller. Built on a high-performance, low-power BiCMOS process, this controller offers a 1A peak current drive capability and fast output rise and fall times of 20ns and 15ns, respectively. It operates within a voltage range of 7.6V to 20V and a temperature range of -40°C to +85°C.

 

This device supports multiple topologies including Buck, Boost, Flyback, and Forward converters, making it versatile for various switched-mode power supply designs. Key features include ultralow startup current (50µA typical) and low operating current (4mA typical), contributing to high efficiency. The controller also includes features like trimmed oscillator discharge current, a trimmed 5V bandgap reference, and UVLO with hysteresis.

 

The MIC38HC43YM-TR is supplied in an 8-SOIC package suitable for surface mounting. Its pin-for-pin compatibility with UC384x bipolar devices simplifies upgrades in existing designs. This controller is well-suited for applications requiring efficient current-mode control in off-line and DC-to-DC converters.
