The MIC38HC45YM 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 such as ultralow startup current (50µA typical) and low operating current (4mA typical). This controller is pin-compatible with bipolar UC384x devices and supports various topologies including buck, boost, flyback, and forward converters.
Key electrical specifications include an operating voltage range of 7.6V to 20V, a maximum duty cycle of 50%, and fast output rise and fall times of 20ns and 15ns, respectively. It features a trimmed 5V bandgap reference and operates at frequencies up to 500kHz. The device is designed for applications requiring high efficiency in switched-mode power supplies and DC-to-DC converters.
The MIC38HC45YM is available in an 8-SOIC package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. The controller includes undervoltage lockout (UVLO) with hysteresis and features CMOS outputs with rail-to-rail swing for increased efficiency, especially at lower supply voltages.
