The MIC2130/1 is a high voltage input PWM synchronous buck controller 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.

8V to 40V input voltage range.
Adjustable output voltages down to 0.7V.
LOW EMI option MIC2131.
Fixed 150kHz and 400kHz frequency options.
Excellent line and load regulation due to fast hysteretic control loop during transients.
Adaptive gate drive allows efficiencies over 95%.
Programmable current limit with no sense resistor.
Senses low-side MOSFET current.
Internal drivers allow 15A output current.
Powe.
