LTC3533 Datasheet 2a Wide Input Voltage Synchronous Buck-boost DC/dc Converter

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®3533 is a wide VIN range, 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 cell lithium-ion/polymer or multi-cell alkaline/NiMH applications where the output voltage is within the input voltage range.
