The TPS552852 is a fully-integrated ,synchronous buck-boost converter that is optimized for converting battery voltage or adapter voltage into power supply rails. The TPS552852 integrates four 15mΩ MOSFETs to provide a high efficiency and small size design.

The TPS552852 has a wide input voltage range from 2.4V (3.0V rising) to 22V and capable of outputting 0.8V to 15V voltage to support a variety of applications. The device features 8A average inductor current limit and can supply up to 7A output current in buck mode.

The TPS552852 offers input and output overvoltage protection, average inductor current limit, cycle-by-cycle peak current limit, and output short-circuit protection. The TPS552852 is also designed for safe operating with output current limit without external output current sense resistor and hiccup mode protection in sustained overload conditions.

The TPS552852 allows the use of small inductor and capacitor with high switching frequency. The TPS552852 is available in a 2.5mm × 3.5mm QFN package.
