The MIC38HC43-1YM-TR from Microchip Technology is a fixed-frequency, current-mode PWM controller featuring 1A drive current capability. Built on a high-performance, low-power BiCMOS process, this controller offers pin-for-pin compatibility with bipolar UC384x devices. It boasts ultralow startup current (50µA typical) and low operating current (4mA typical), contributing to high efficiency.
Key electrical specifications include an operating voltage range of 7.6V to 20V and an operating temperature range of -40°C to 85°C. The controller supports current-mode operation up to 500kHz and features fast output rise (20ns) and fall (15ns) times. It has a maximum duty cycle of 96% and provides a trimmed 5V bandgap reference.
The device is suitable for various power supply applications, including off-line and DC-to-DC converters, step-down (buck) regulators, step-up (boost) regulators, flyback, and forward converters. The MIC38HC43-1YM-TR is supplied in a 14-SOIC package, designed for surface mounting.
