Product Overview

The LTC1878EMS8#PBF is a high-efficiency monolithic synchronous Buck Regulator using a constant frequency and current-mode architecture. Supply current during operation is only 10µA and drops to <1µA in shutdown. The 2.65 to 6V input voltage range makes the LTC1878 ideally suited for single Li-ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. Switching frequency is internally set at 550kHz, allowing the use of small surface mount inductors and capacitors. For noise sensitive applications the LTC1878 can be externally synchronized from 400 to 700kHz. Burst Mode® operation is inhibited during synchronization or when the SYNC/MODE pin is pulled low, preventing low frequency ripple from interfering with audio circuitry. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.8V feedback reference voltage.
  • No Schottky diode required
  • Current-mode control for excellent line and load transient response
  • Overcurrent and over-temperature protection
  • Up to 95% high efficiency
  • Very low quiescent current of only 10µA during operation
  • ±2% Output voltage accuracy
