General Description

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.

Key Features

  • 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.
