The TPS63820, TPS638201 and TPS638202 are low quiescent current, high output current buck-boost converters fully programmable through I2C. The 2.3µA quiescent current and four low Rdson MOSFETs enable high efficiency from a light to a heavy load range.

Depending on the input voltage, the devices automatically operate in boost, buck, or in buck-boost mode when the input voltage is approximately equal to the output voltage. The transitions between modes occur at defined thresholds and avoid unwanted toggling within the modes which reduces output voltage ripple.

The devices have a fast dynamic response, which enables the regulation of output voltage tightly, even in the event of heavy load transients.

The devices offer a small design size in WCSP. The design size is < 20mm2 with only four external components.
