1.5A output current, buck-boost MicroSiP™ power module with integrated inductor with I²C

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. 8µA 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.
