LTC3633 - Dual Channel 3A 15V Monolithic Synchronous Step-Down Regulator

Datasheet Summary

Description

The LTC®3633 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, which relaxes the requirements for input and output capacitance.

Features

  • n 3.6V to 15V 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 Operation n Output Voltage Tracking and Soft-.
