The TPS552892 is a synchronous buck-boost converter that is optimized for converting battery voltage or adapter voltage into power supply rails. The TPS552892 integrates four MOSFET switches providing a compact solution for a variety of applications. The TPS552892 has up to 36V input voltage capability. When working in boost mode, the TPS552892 can deliver 60 W from a 12-V input. It is capable of delivering 45 W from 9-V input voltage.

The TPS552892 employs an average current-mode control scheme. The switching frequency is programmable from 200 kHz to 2.2 MHz by an external resistor and can be synchronized to an external clock. The TPS552892 also provides optional spread spectrum to minimize peak EMI.

The TPS552892 offers output over-voltage protection, average inductor current limit, cycle-by-cycle peak current limit, output short circuit protection. The TPS552892 also ensures safe operating with optional output current limit and hiccup-mode protection in sustained overload conditions.

The TPS552892 can use a small inductor and small capacitors with high switching frequency. The TPS552892 is available in a 3.0-mm × 5.0-mm QFN package.
