Product Overview

The LTC3533EDE#PBF is a 2A wide input voltage synchronous buck-boost DC/DC Converter operates from input voltages above, below or equal to the output voltage. The topology incorporated in the IC provides a continuous transfer function through all operating modes, making the product ideal for single cell lithium-ion/polymer or multi-cell alkaline/NiMH applications where the output voltage is within the input voltage range. The LTC3533 features programmable Burst Mode® operation, extended VIN and VOUT ranges down to 1.8V and increased output current. Switching frequencies up to 2MHz are programmed with an external resistor. The Burst Mode® threshold is programmed with a single resistor from the BURST pin to GND. Other features include 1µA shutdown current, short-circuit protection, programmable soft-start, current limit and thermal shutdown.
  • Regulated output with input voltages above, below or equal to the output
  • 0.8A Continuous output current (VIN >1.8V)
  • 2A Continuous output current (VIN >3V)
  • Single inductor
  • Synchronous rectification up to 96% efficiency
  • Programmable Burst Mode® operation (IQ = 40µA)
  • Output disconnect in shutdown
  • Programmable frequency from 300kHz to 2MHz
  • <1µA Shutdown current
