LT3972 - 2.4MHz Step-Down Switching Regulator

General Description

The LT®3972 is an adjustable frequency (200kHz to 2.4MHz) monolithic buck switching regulator that accepts input voltages up to 33V (62V maximum).

A high efficiency 95mΩ switch is included on the die along with a boost Schottky diode and the necessary oscillator, control and logic circuitry.

Key Features

  • Wide Input Range: Operation from 3.6V to 33V Overvoltage Lockout Protects Circuits Through 62V Transients.
  • 3.5A Maximum Output Current.
  • Low Ripple (.
