Product Overview

The LTC1627IS8#PBF is a monolithic current-mode synchronous Buck Regulator using a fixed frequency architecture. The operating supply range is from 8.5V down to 2.65V, making it suitable for one or two lithium-ion battery-powered applications. Burst Mode® operation provides high efficiency at low load currents. 100% duty cycle provides low dropout operation, which extends operating time in battery-operated systems. The operating frequency is internally set at 350kHz, allowing the use of small surface mount inductors. For switching noise sensitive applications it can be externally synchronized up to 525kHz. The SYNC/FCB control pin guarantees regulation of secondary windings regardless of load on the main output by forcing continuous operation. Burst Mode® operation is inhibited during synchronization or when the SYNC/FCB pin is pulled low to reduce noise and RF interference. Soft-start is provided by an external capacitor.
  • No Schottky diode required
  • Secondary winding regulation
  • Current-mode operation for excellent line and load transient response
  • Up to 96% high efficiency
  • Precision 2.5V undervoltage lockout
  • Shutdown mode draws only 15µA supply current
  • 200µA Low quiescent current
  • ±1.5% Reference accuracy
