Product Overview

The LTC3633AIUFD-2#PBF is a dual-channel high efficiency 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 to relax the requirements for input and output capacitance. The operating supply voltage range is from 3.6 to 20V, making it suitable for lithium-ion battery stacks as well as point of load power supply applications from a 12 or 5V supply. The operating frequency is programmable from 500kHz to 4MHz with an external resistor and may be synchronized to an external clock signal. 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 locked 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
