Product Overview

The LTC3565IMSE#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 0.6 to 5.5V. Internal synchronous power switches provide high efficiency. The LTC3565's current-mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. The LTC3565 can be configured for automatic power saving Burst Mode® operation (IQ=40µA) to reduce gate charge losses when the load current drops below the level required for continuous operation. For reduced noise and RF interference, the SYNC/MODE pin can be configured to skip pulses or provide forced continuous operation.
  • Stable with ceramic capacitors
  • Current-mode operation for excellent line and load transient response
  • Short-circuit protection
  • Synchronizable to external clock
  • Supports pre-biased outputs
  • Up to 95% high efficiency
  • Low dropout operation - 100% duty cycle
  • Low shutdown current of IQ <=1µA
  • 0.15R Low RDS(ON) internal switches
