Product Overview

The LTC3561AEDD#PBF is a constant-frequency synchronous step-down DC-to-DC Converter intended for medium power applications. It operates from a 2.5 to 5.5V input voltage range and has a user configurable operating frequency up to 4MHz, allowing the use of tiny, capacitors and inductors 1mm or less in height. The output voltage is adjustable from 0.8 to 5.5V. Internal synchronous power switches provide high efficiency. The LTC3561A'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). 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
  • Up to 96% high efficiency
  • 0.15R Low RDS(ON) internal switches
  • 330µA Low quiescent current
