Texas Instruments TPS631010 | Demoboard TPS631010EVM-109

Beschreibung

The TPS631010 and TPS631011 are constant frequency peak current mode control buck-boost converters in tiny wafer chip scale package. They have 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.
