Description
General part information
LTC3532 Series
The LTC3532 is a high efficiency, fixed frequency, buck-boost DC/DC converter that 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 lithium-ion, multicell alkaline or NiMH applications where the output voltage is within the battery voltage range.The device includes two 0.36Ω N-channel MOSFET switches and two 0.42Ω P-channel switches. Switching frequencies up to 2MHz are programmed with an external resistor. Quiescent current is only 35μA in Burst Mode operation, maximizing battery life in portable applications. Automatic Burst Mode operation allows the user to program the load current for Burst Mode operation or to control it manually.Other features include a 1μA shutdown, soft-start control, thermal shutdown, and peak current limit. The LTC3532 is available in a low profile (0.75mm) 10-lead (3mm × 3mm) DFN and 10-lead MSOP packages.ApplicationsMiniature Hard Disk Drive Power SupplyMP3 PlayersHandheld InstrumentsDigital CamerasHandheld Terminals
