MIC38C42YM-TR

AC DC Converters, Offline Switchers Overview

The MIC38C42YM-TR is a monolithic high-speed switching mode power supply (SMPS) controller manufactured by Microchip Technology. It operates as a BiCMOS current-mode PWM controller supporting Boost, Buck, Flyback, and Forward topologies. The device features a fixed switching frequency of 500 kHz and supports a maximum duty cycle of 96%. It functions within an input voltage range of 9V to 20V with a maximum operating voltage of 14.5V. The controller provides a regulated output voltage of 5V at up to 1A output current capability. It is housed in an 8-SOIC surface-mount package and operates reliably across a temperature range of -40°C to +85°C.

AC DC Converters, Offline Switchers Feature Summary

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official documentation prior to procurement. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Check for moisture sensitivity level requirements during storage and handling procedures.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring a single-output SMPS controller with integrated current-mode control. The 500 kHz frequency allows for compact passive component sizing. Ensure the application voltage does not exceed the 14.5V absolute maximum rating. Consider the SOIC-8 package constraints for thermal management and PCB layout space.

AC DC Converters, Offline Switchers Part Context

This part belongs to the MIC38C42 family of BiCMOS current-mode PWM controllers from Microchip Technology. It shares functional similarities with other variants like the MIC38HC43 series but differs in specific pinouts and electrical characteristics. The family is designed for efficient offline and isolated DC-DC conversion solutions.

AC DC Converters, Offline Switchers Replacement Considerations

Direct substitutes include MIC38C42YM without the reel suffix or MIC38C42ABM for different packaging needs. Verify pin compatibility and electrical specifications before substituting with generic current-mode PWM controllers.
