Product Overview

The LTC3615EUF#PBF is a dual 3A synchronous Step Down Regulator using a current mode, constant-frequency architecture. The DC supply current is only 130µA while maintaining the output voltages, dropping to zero current in shutdown. The 2.25 to 5.5V input supply range makes the parts ideally suited for single Li-Ion applications. 100% duty cycle capability provides low dropout operation, which extends operating time in battery-operated systems. The operating frequency is externally programmable up to 4MHz, allowing the use of small surface mount inductors. The phase shift between the two channels can be selected to minimize input current ripple and output voltage ripple in a dual 3A or single 6A output configuration. Programmable slew rate limiting reduces EMI and external synchronization can be applied up to 4MHz. The internal synchronous switches increase efficiency and eliminate the need for external catch diodes, saving external components and board space.
  • Programmable slew rate at switch pins
  • Adjustable switching frequency up to 4MHz
  • Internal or external compensation
  • Selectable pulse-skipping/forced continuous/burst mode operation with adjustable burst clamp
  • Fixed internal and programmable external soft-start
  • Accurate start-up tracking capability
  • Up to 94% high efficiency
  • ±1% Output voltage accuracy
  • <=1µA Shutdown current
