LTC3633A-1 - Monolithic Synchronous Step-Down Regulator

Download the LTC3633A-1 datasheet PDF. This datasheet also covers the LTC3633A variant, as both devices belong to the same monolithic synchronous step-down regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LTC®3633A is a high efficiency, dual-channel monolithic synchronous buck regulator using 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.

Key Features

  • n 3.6V to 20V Input Voltage Range n 3A Output Current per Channel n Up to 95% Efficiency n Low Duty Cycle Operation: 5% at 2.25MHz n Selectable 0°/180° Phase Shift Between Channels n Adjustable Switching Frequency: 500kHz to 4MHz n External Frequency Synchronization n Current Mode Operation for Excellent Line and Load Transient Response n 0.6V Reference Allows Low Output Voltages n User Selectable Burst Mode® Operation or Forced Continuous Mode Operation n Output Voltage Tracking and Soft-Start.
