Product Overview

The LTC3407IDD-2#PBF is a dual constant frequency synchronous step-down DC/DC Regulator intended for low power applications, it operates from a 2.5 to 5.5V input voltage range and has a constant 2.25MHz switching frequency, enabling the use of tiny, low cost capacitors and inductors 1mm or less in height. Each output voltage is adjustable from 0.6 to 5V. Internal synchronous 0.35R, 1.2A power switches provide high efficiency without the need for external Schottky diodes. A user selectable mode input is provided to allow the user to trade-OFF ripple noise for low power efficiency. Burst Mode® operation provides the highest efficiency at light loads, while Pulse Skip Mode provides the lowest ripple noise at light loads. To further maximize battery life, the P-channel MOSFETs are turned on continuously in dropout (100% duty cycle) and both channels draw a total quiescent current of only 40µA. In shutdown, the device draws <1µA.
  • No Schottky diodes required
  • Current mode operation for excellent line and load transient response
  • Short-circuit protected
  • Power-ON reset output
  • Externally synchronizable oscillator
  • Up to 95% high efficiency
  • 100% Duty cycle low dropout operation
  • <1µA Ultra-low shutdown current
