Product Overview

The LT3431IFE#PBF is a monolithic buck Switching Regulator accepts input voltage up to 60V. A high efficiency 3A, 0.1R switch is included on the die along with all the necessary oscillator, control and logic circuitry. A current-mode architecture provides fast transient response and good loop stability. Special design techniques and a new high voltage process achieve high efficiency over a wide input range. Efficiency is maintained over a wide output current range by using the output to bias the circuitry and by utilizing a supply boost capacitor to saturate the power switch. Patented circuitry maintains peak switch current over the full duty cycle range. A shutdown pin reduces supply current to 30µA and the device can be externally synchronized from 580 to 700kHz with logic level inputs.
  • Peak switch current maintained over full duty cycle range
  • Easily synchronizable
  • Cycle-by-cycle current limiting
  • 0.1R Saturating switch design
  • 2.5mA Effective supply current
  • 1.2V Feedback reference voltage
