The MIC38HC44YM-TR from Microchip Technology is a fixed-frequency, current-mode PWM controller with 1A drive current capability. Built on a high-performance, low-power BiCMOS process, it offers advantages like ultralow startup current (50µA typical) and low operating current (4mA typical).
This controller features a wide operating voltage range of 9V to 20V and can operate at frequencies up to 500kHz. The MIC38HC44YM-TR has a maximum duty cycle of 50% and provides fast output rise and fall times of 20ns and 15ns, respectively. Its outputs are CMOS with rail-to-rail swing, increasing efficiency, especially at lower supply voltages.
Designed for applications such as off-line and DC-to-DC switched-mode power supplies, including buck, boost, flyback, and forward converters, the MIC38HC44YM-TR is housed in an 8-SOIC surface-mount package. It operates within a temperature range of -40°C to +85°C, with some sources indicating up to 150°C junction temperature.
