Product Overview

The LTC3561EDD#PBF is a constant-frequency synchronous step-down DC-to-DC Converter intended for medium power applications. It operates from a 2.63 to 5.5V input voltage range and has a user configurable operating frequency up to 4MHz, allowing the use of tiny, capacitors and inductors 2mm or less in height. The output voltage is adjustable from 0.8 to 5.5V. Internal synchronous 0.11R power switches with 1.4A peak current ratings provide high efficiency. The LTC3561's current-mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. To further maximize battery life, the P-channel MOSFET is turned on continuously in dropout (100% duty cycle). The no-load quiescent current is only 240µA. In shutdown, the device draws <1µA.
  • Uses tiny capacitors and inductor
  • Stable with ceramic capacitors
  • Current-mode operation for excellent line and load transient response
  • Short-circuit protection
  • Low noise pulse-skipping operation
  • Up to 95% high efficiency
  • 0.110R Low RDS(ON) internal switches
