1.4 Device Information

The TPS552852 is a fully integrated synchronous buck-boost converter that is optimized for converting battery voltage or adaptor voltage into power supply rails. The TPS552852 integrates four 15mΩ MOSFETs to provide a high efficiency and small size solution. It features 8A average inductor current limit and can supply up to 7A output current in buck mode. When working in boost mode, it can deliver 60W from 12V input or 30W from 5V input. The TPS552852 offers input and output over-voltage protection, average inductor current limit, cycle-by-cycle peak current limit and output short circuit protection. The TPS552852 also ensures safe operating with output current limit without external output current sense resistor and hiccup mode protection in sustained overload conditions.

The factory default settings of the TPS552852EVM allow the operation with an input voltage range from 2.4V to 22V and a 12V output voltage. Customer can adjust the output voltage by changing the FB divider resistance and adjust output current limit by changing the ILIM resistor.
