The MIC2130/1 is a high voltage input PWM synchronous buck IC. It is a voltage mode controller with a fast hysteretic control loop (FHyCL) employed during fast line and load transients. The internal gate drivers are designed to drive high current MOSFETs.

The MIC2130/1 can produce output voltages down to 0.7V with input voltage from 8V to 40V. The MIC2130 family of control ICs implements fixed frequency PWM control. The active anti-shoot through drive scheme means a wide range of external MOSFETs may be used while maintaining optimum efficiency.

The MIC2131 is the fully functional version of the family and implements a new feature to minimize EMI. This function is critical for systems that need to be compliant with EMI standards throughout the world.

The MIC2130/1 is available in small size 16-pin 4mm x 4mm MLF? package, as well as 16-pin e-TSSOP at a junction temperature range of -40°C to +125°C.
