MIC3839YMM Description

Short technical summary and product information.

The MIC3839YMM from Microchip Technology is a flexible push-pull PWM controller IC designed for high-speed, low-power applications. It is suitable for telecom-level isolated step-down DC/DC conversion where high output current, small size, and high efficiency are required.

 

This controller features a configurable voltage-mode or current-mode control and can implement a volt-second clamp for automatic duty cycle limiting during input transients. Key electrical specifications include an operating voltage range of 2V to 14V, a maximum duty cycle of 49%, and a switching frequency of 200kHz. It also offers a typical start-up current of 130 µA and a typical run current of 1 mA.

 

The MIC3839YMM is available in a compact 10-MSOP package, designed for surface mounting. Its operating temperature range is -40°C to 85°C (TA), making it suitable for various environmental conditions. The device supports multiple topologies including full-bridge, half-bridge, and push-pull configurations.

 

This controller is ideal for applications requiring efficient power conversion, such as telecom equipment, industrial power supplies, and automotive power supplies. Its design facilitates smaller DC/DC solutions and reduces input/output ripple stress on external components.
