Description
General part information
LTC3530 Series
The LTC3530 is a wide VINrange, highly efficient, 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, two-cell alkaline or NiMH applications where the output voltage is within the battery voltage range.The LTC3530 is pin compatible with the LTC3440 buckboost DC/DC converter but adds programmable automatic Burst Mode operation and extends the VIN/VOUTrange to 1.8V. Switching frequencies up to 2MHz are programmed with an external resistor. Automatic Burst Mode operation allows the user to program the load current threshold for Burst Mode operation using a single resistor from the BURST pin to GND.Other features include 1µA shutdown, short circuit protection, programmable soft-start control, current limit and thermal shutdown. The LTC3530 is available in a thermally enhanced 10-lead (3mm × 3mm) DFN or MSOP package.ApplicationsMP3 PlayersHandheld InstrumentsDigital CamerasSmart PhonesPortable GPS UnitsMiniature Hard Disk Drive Power
