Product Overview

The LTC3612EFE#PBF is a monolithic synchronous Buck Regulator using a current mode and constant frequency architecture. The no-load DC supply current in sleep mode is only 70µA while maintaining the output voltage (Burst Mode® operation) at no load, dropping to zero current in shutdown. The 2.25 to 5.5V input supply voltage range makes the LTC3612 ideally suited for single Li-ion as well as fixed low voltage input applications. 100% duty cycle capability provides low dropout operation, extending the operating time in battery-powered systems. The operating frequency is externally programmable up to 4MHz, allowing the use of small surface mount inductors. For switching noise-sensitive applications, the LTC3612 can be synchronized to an external clock at up to 4MHz. Forced continuous mode operation in the LTC3612 reduces noise and RF interference. Adjustable compensation allows the transient response to be optimized over a wide range of loads and output capacitors.
  • Inputs for start-up tracking or external reference
  • Up to 95% high efficiency
  • ±1% Output voltage accuracy
  • <=1µA Shutdown current
  • ±1.5A DDR memory mode (IOUT)
