MIC2131-4YTSE Description

Short technical summary and product information.

The MIC2131-4YTSE from Microchip Technology is a high voltage input PWM synchronous buck controller IC. It features a voltage mode controller with a fast hysteretic control loop (FHyCL) for handling fast line and load transients. The internal gate drivers are designed to drive high current MOSFETs, enabling output voltages down to 0.7V with an input voltage range of 8V to 40V.

 

This controller IC implements fixed frequency PWM control with an active anti-shoot through drive scheme. The MIC2131 variant includes a feature to minimize EMI, which is critical for systems requiring compliance with global EMI standards. It operates at a fixed frequency of 400kHz and offers features such as programmable current limit, power good output, and programmable soft-start.

 

The MIC2131-4YTSE is available in a 16-pin e-TSSOP package. It is suitable for applications including industrial/medical DC/DC point of use power, printer head drivers, automotive systems, telecom systems, LCD/Plasma TVs, and gaming machines. The device operates within a junction temperature range of -40°C to +125°C.
