Product Introduction
The TPS631010 and TPS631011 are constant frequency peak current mode control buck - boost converters in tiny wafer chip scale package. They have a 3 - A peak current limit (typical) and 1.6 - V to 5.5 - V input voltage range, and provide a power supply solution for system pre - regulators and voltage stabilizers.
Depending on the input voltage, the TPS631010 and TPS631011 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 devices offer a very small solution size in WCSP.
