MIC21LV32 - Advanced COT Buck Controller

Description

The MIC21LV32 is a constant on-time, dual phase synchronous buck controller featuring a unique adaptive on-time control architecture with stackable feature up to eight phases.

The MIC21LV32 operates over an input supply range from 4.5V to 36V and can be used to supply up to 50A of output current.

Features

  • Input Voltage Range: 4.5V to 36V.
  • Input Down to 2V when VDD = 5V from External Supply.
  • Adjustable Output Voltage from 0.6V to 28V.
  • Adaptive Constant On-Time Control: - High DeltaV operation - Any Capacitor™ stable.
  • 0.6V Internal Reference with ±1% Accuracy.
  • Novel Ripple Injection Method to Allow Greater than 50% Duty Cycle Operation.
  • Operates in CCM, Stackable for Multiphase Operation up to Eight Phases.
  • Accurate Current Ba.
