The TPS631000 is a constant frequency peak current mode control buck-boost converter. The device has a 3-A peak current limit (typical) and 1.6-V to 5.5-V input voltage range. The TPS631000 provides a power supply solution for system pre-regulators and voltage stabilizers.

Depending on the input voltage, the TPS631000 automatically operates 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 TPS631000 offers a very small solution size with a 1.2-mm × 2.1-mm SOT-583 package, a 1-µH inductor, and one 0805 output capacitor.
