General Description

The LTC®3534 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 multi-cell Alkaline/NiMH or single Lithium-Ion/Polymer applications where the output voltage is within the battery voltage range.

The LTC3534 offers extended VIN and VOUT ranges of 2.4V to 7V and 1.8V to 7V, respectively.
