Product Overview

The LTC3531EDD#PBF is a 200mA synchronous buck-boost DC/DC Converter operates from input voltages above, below or equal to the output voltage. The topology incorporated in the ICs provides a continuous transfer through all operating modes, making the product ideal for single cell Li-ion and multicell alkaline or nickel applications. The converters operate in Burst Mode®, minimizing solution footprint and component count as well as providing high conversion efficiency over a wide range of load currents. The devices include two 0.5R N-channel MOSFET switches and two P-channel switches (0.5, 0.8R). Quiescent current is typically 16µA, making the parts ideal for battery power applications. Other features include a <1µA shutdown current, current limiting, thermal shutdown and output disconnect.
  • Regulated output with input above, below or equal to the output
  • Single inductor
  • Up to 90% efficiency
  • 200mA at 3.3VOUT from 3.6V input
  • 125mA at 3VOUT from 2.5V input
  • Fixed VOUT Versions (3.3, 3V)
  • Adjustable VOUT Version (DFN, 2 to 5V)
  • Burst Mode® operation, no external compensation
  • Ultra low quiescent current (16µA), <1µA shutdown current
  • Only 3 external components required (fixed voltage versions)
  • Short-circuit protection
  • Output disconnect in shutdown
