MIC3808YM-TR

AC DC Converters, Offline Switchers Overview

The MIC3808YM-TR is a push-pull DC/DC controller manufactured by Microchip Technology, housed in an SOIC-8 surface-mount package. It operates within a temperature range of -40°C to +85°C and features a switching frequency of 200 kHz with a maximum duty cycle of 50%. The device provides two adjustable outputs with a drive current capability of 10 mA. Key electrical characteristics include rise and fall times of 25 ns, an isolated topology, and a typical operating supply current of 1 mA.

AC DC Converters, Offline Switchers Feature Summary

• Complementary output push-pull architecture for efficient transformer utilization
• High-speed operation with low power consumption
• Out-of-phase topology to reduce input and output ripple

AC DC Converters, Offline Switchers Applications

• Telecom level isolated step-down DC/DC conversion
• Applications requiring high output current and small size
• High efficiency power supply designs

AC DC Converters, Offline Switchers Procurement Notes

Verify the suffix 'TR' indicates tape-and-reel packaging distinct from tube variants. Confirm RoHS compliance status via official documentation as it may vary by revision. Ensure the SOIC-8 package dimensions match PCB footprint requirements. Check humidity sensitivity classification for storage and handling protocols prior to assembly.

AC DC Converters, Offline Switchers Selection Notes

Select this component for applications requiring a dedicated push-pull controller rather than integrated converters. The 200 kHz frequency balances efficiency and component size. Verify that the 10 mA output drive current suffices for the intended gate driver or transformer primary circuitry without external buffering.

AC DC Converters, Offline Switchers Part Context

This part belongs to the MIC3808/MIC3809 family of complementary output push-pull PWM control ICs. These devices are designed for telecom-level isolated step-down DC/DC conversion where high output current, small size, and high efficiency are required. The dual-ended push-pull architecture allows more efficient utilization of the transformer compared to single-ended topologies.

AC DC Converters, Offline Switchers Replacement Considerations

MIC3808BM is a compatible variant within the same family offering similar functionality in an SOIC-8 package.
