The TPSM83100 and TPSM83101 are constant frequency peak current mode control buck-boost MicroSiP™ power modules optimized for small solution size and high efficiency. The power modules integrate an inductor to simplify design, reduce external components and save PCB area. They have a 3-A peak current limit (typical) and 1.6-V to 5.5-V input voltage range. The TPSM83100 and TPSM83101 provide a power supply solution for system pre-regulators and voltage stabilizers.

Depending on the input voltage, the TPSM83100 and TPSM83101 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 enable the highest efficiency for light to no-load conditions.
