Product Overview

The LTC3538EDCB#TRMPBF is a highly efficient low noise buck-boost DC-to-DC Converter operates from input voltages above, below and 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 lithium-ion or multicell Alkaline or NiMH applications where the output voltage is within the battery voltage range. The LTC3538 is suited for use in micro hard disk drive (MHDD) applications with its 800mA current capability. Burst Mode® operation provides high efficiency at light loads. The LTC3538 includes two 0.17R N-channel and two 0.2R P-channel MOSFET switches. Operating frequency is internally set to 1MHz to minimize solution footprint while maximizing efficiency. Other features include <5µA shutdown current, internal soft-start, short-circuit protection and thermal shutdown.
  • Single inductor
  • Output disconnect in shutdown
  • Internal soft-start
  • 35µA Quiescent current in Burst Mode® operation
