Product Overview

The LTC3417EFE#PBF is a dual constant frequency synchronous step-down DC/DC Converter intended for medium power applications, it has a constant programmable switching frequency, allowing the use of tiny capacitors and inductors 2mm or less in height. Each output voltage is adjustable from 0.8 to 5V. Internal synchronous low RDS (ON) power switches provide high efficiency without the need for external Schottky diodes. A user selectable mode input allows the user to trade off ripple voltage for light load efficiency. Burst Mode® operation provides high efficiency at light loads, while Pulse Skip mode provides low ripple noise at light loads. A phase mode pin allows the second channel to operate in-phase or 180° out-of-phase with respect to channel 1. Out-of-phase operation produces lower RMS current on VIN and thus lower RMS derating on the input capacitor.
  • Up to 95% high efficiency
  • No Schottky diodes required
  • Short-circuit protected
  • Current mode operation for excellent line and load transient response
  • Power good output
  • Phase pin selects 2nd channel phase relationship with respect to 1st channel
  • Internal soft-start with individual run pin control
  • 125µA Quiescent current in sleep mode
  • 1µA Ultra-low shutdown current
  • 100% Duty cycle low dropout operation
