The MIC38HC45-1YN from Microchip Technology is a fixed-frequency, current-mode PWM controller with a 1A drive current capability. Built on Micrel's BiCMOS process, it offers high performance and low power consumption, making it ideal for applications requiring high efficiency.
Key electrical specifications include an ultralow startup current of 50µA typical and a low operating current of 4mA typical. It boasts fast output rise and fall times of 20ns and 15ns, respectively, and supports current-mode operation up to 500kHz. The device operates within a voltage range of 7.6V to 20V and features a trimmed 5V bandgap reference.
This controller is pin-compatible with bipolar UC384x devices and supports various topologies including Buck, Boost, Flyback, and Forward converters. It is suitable for applications such as off-line and DC-to-DC switched-mode power supplies.
The MIC38HC45-1YN is available in a 14-pin DIP package, designed for through-hole mounting. Its operating temperature range is -40°C to +85°C.
