The TPSM83102 and TPSM83103 are constant frequency peak current mode control buck-boost converters in samll µSiP module package. It has a 3A peak current limit (typical) and 1.6V to 5.5V input voltage range, and provide a power supply solution for system pre-regulators and voltage stabilizers.

Depending on the input voltage, the TPSM83102 and TPSM83103 automatically operate in boost, buck, or in 3-cycle buck-boost mode when the input voltage is approximately equal to the output voltage. The transitions between modes happen at a defined duty cycle and avoid unwanted toggling within the modes to reduce output voltage ripple. 8-µA quiescent current and power save mode power enable the highest efficiency for light to no-load conditions.

The device offers a very small solution size in µSiP module package.
