The MIC38C42BN by Microchip Technology is a high-performance, fixed-frequency, current-mode PWM controller. Built on a low-power BiCMOS process, it offers improved performance over bipolar 384x devices.
Key electrical specifications include an operating voltage range of 9V to 20V, a startup voltage of 14.5V, and a switching frequency of 500kHz. It supports a duty cycle of up to 96% and features a trimmed 5V bandgap reference. The controller boasts fast output rise and fall times, with the MIC38C42 variant offering 40ns rise and 30ns fall times.
This device is designed for applications such as off-line and DC-to-DC switched-mode power supplies, including buck, boost, flyback, and forward converters. It is housed in an 8-DIP package and is suitable for through-hole mounting.
The operating temperature range for the MIC38C42BN is -40°C to 150°C (TJ). It features ultralow start-up current (50 μA typical) and low operating current (4mA typical), contributing to overall efficiency.
