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.

The operating supply voltage range is from 3.6V to 20V, making it suitable for lithium-ion battery stacks as well as point of load power supply applications from a 12V or 5V supply.

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.
