Product Overview

LTC®3633A-2 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 points of load power supply applications from a 12V 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. It can select between forced continuous mode and high efficiency Burst Mode operation. Application includes distributed power systems, battery-powered instruments, point of load power supplies.
  • 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, power good status outputs
  • Short-circuit protected, overvoltage input and overtemperature protection
  • Supply range from 3.6 to 20V (TJ = 25°C, PVIN1 = PVIN2 = SVIN = 12V)
  • Typical feedback reference voltage is 0.6V (TJ = 25°C, PVIN1 = PVIN2 = SVIN = 12V)
  • Typical error amplifier transconductance is 1.8ms (ITH = 1.2V, TJ = 25°C)
  • 28-lead plastic TSSOP package
  • Temperature rating range from -40°C to 125°C
