Product Overview

The LTC3614HUDD#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 75µA 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 LTC3614 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 LTC3614 can be synchronized to an external clock at up to 4MHz. Forced continuous mode operation in the LTC3614 reduces noise and RF interference. Adjustable compensation allows the transient response to be optimized over a wide range of loads and output capacitors.
  • Programmable slew rate on SW node reduces noise and EMI
  • Programmable soft-start
  • Inputs for start-up tracking or external reference
  • Up to 95% high efficiency
  • ±1% Output voltage accuracy
  • ±3A DDR memory mode (IOUT)
