Product Overview

The LTC1879EGN#PBF is a high-efficiency monolithic synchronous Buck Regulator using a constant frequency and current-mode architecture. Operating supply current is only 15µA with no load and drops to <1µA in shutdown. The input supply voltage range of 2.65 to 10V makes the LTC1879 ideally suited for both single and dual Li-ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. The switching frequency is internally set to 550kHz, allowing the use of small surface mount inductors and capacitors. For noise sensitive applications, the LTC1879 can be externally synchronized from 350 to 750kHz. Burst Mode® operation is inhibited during synchronization or when the SYNC/MODE pin is pulled low. The internal synchronous rectifier switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with a 0.8V feedback reference voltage.
  • Power good output voltage monitor
  • Current-mode operation for excellent line and load transient response
  • Overcurrent and over-temperature protection
  • Up to 95% high efficiency
  • Low quiescent current of only 15µA with no load
  • ±2% Output voltage accuracy
