MIC2131 - High Voltage Synchronous Buck Controller

Download the MIC2131 datasheet PDF. This datasheet also covers the MIC2130 variant, as both devices belong to the same high voltage synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

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.

MIC2130/1 High Voltage Synchronous Buck Control IC with Low EMI Option 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. 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.
