Product Overview

The LTC3633EFE#PBF is a dual-channel monolithic Synchronous Buck Regulator uses a controlled on-time, current mode architecture, with phase lockable switching frequency. The two channels can run 180° out of phase, which relaxes the requirements for input and output capacitance. The operating supply voltage range is from 3.6 to 15V, making it suitable for dual cell lithium-ion batteries as well as point of load power supply applications from a 12 or 5V supply. The operating frequency is programmable and synchronizable from 500kHz to 4MHz with an external resistor. The high frequency capability allows the use of small surface mount inductors and capacitors. The unique constant frequency/controlled on-time architecture is ideal for high step-down ratio applications that operate at high frequency while demanding fast transient response. An internal phase lock loop servos the on-time of the internal one-shot timer to match the frequency of the internal clock or an applied external clock.
  • Up to 95% efficiency
  • External frequency synchronization
  • Current mode operation for excellent line and load transient response
  • User selectable Burst Mode® operation or forced continuous operation
  • Output voltage tracking and soft-start capability
  • Short-circuit protected
  • Overvoltage input and overtemperature protection
  • Power good status outputs
