Texas Instruments TPS63802 | Demoboard TIDA-010053

Description

The TPS63802 is a high efficiency, high output current buck-boost converter. It is used when the input voltage is higher, equal, or lower than the output voltage. Output currents up to 2 A are supported over a wide voltage range. The device limits the peak current at 4.5 A in Boost-Mode and 3.5 A in Buck-Mode. The device is adjusted to the programmed output voltage. It automatically changes from buck to boost operation based on the input voltage. It remains in a 3-cycle buck-boost mode when the input voltage is approximately equal to the output voltage. The transitions happen seamlessly and avoids unwanted toggling within the modes. The TPS63802 comes in a 2 mm x 3 mm package. The device works with tiny passive components to keep the overall solution size small.
