Product Overview

The LTC1707CS8#PBF is a high-efficiency monolithic current-mode synchronous Buck Regulator using a fixed frequency architecture. The operating supply range is from 8.5V down to 2.85V, making it suitable for both single and dual lithium-ion battery-powered applications. Burst Mode® operation provides high efficiency at low load currents. 100% duty cycle provides low dropout operation, extending operating time in battery-powered systems. The switching frequency is internally set at 350kHz, allowing the use of small surface mount inductors. For noise sensitive applications it can be externally synchronized up to 550kHz. 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. Soft-start is provided by an external capacitor. The internal synchronous MOSFET switch increases efficiency and eliminates the need for an external Schottky diode, saving components and board space.
  • No Schottky diode required
  • Current-mode control for excellent line and load transient response
  • Up to 96% high efficiency
  • Precision 2.7V undervoltage lockout
  • Shutdown mode draws only 11µA supply current
  • 1.19V ±1% Reference output pin
  • 200µA Low quiescent current
