The TPS552882-Q1 is a synchronous four-switch buck-boost converter capable of regulating the output voltage at, above, or below the input voltage. The TPS552882-Q1 operates over 2.7-V to 36-V wide input voltage and is capable of outputing 0.8-V to 22-V voltage to support a variety of applications.

The TPS552882-Q1 integrates two 16-A MOSFETs of the boost leg to balance the solution size and efficiency. The TPS552882-Q1 uses external resistor divider to set the output voltage with 1.2-V intenral reference voltage. The TPS552882-Q1 is capable of delivering 100 W from 12-V input voltage.

The TPS552882-Q1 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 TPS552882-Q1 also provides optional spread spectrum to minimize peak EMI.

The TPS552882-Q1 offers output overvoltage protection, average inductor current limit, cycle-by-cycle peak current limit, and output short circuit protection. The TPS552882-Q1 also ensures safe operating with optional output current limit and hiccup-mode protection in sustained overload conditions.

The TPS552882-Q1 can use a small inductor and small capacitors with high switching frequency. It is available in a 4.0-mm × 3.5-mm QFN package.
