Description

The TPS55288 is a synchronous four-switch buck-boost converter capable of regulating the output voltage at, above, or below the input voltage. The TPS55288 operates over 2.7-V to 36-V wide input voltage and capable of outputing 0.8-V to 22-V voltage to support a variety of applications.

The TPS55288 integrates two 16-A MOSFETs of the boost leg to balance the solution size and efficiency. With the programmable output voltage and output current limit through I²C interface, the TPS55288 is fully compliant to the USB PD specification. The TPS55288 is capable of delivering 100 W from 12-V input voltage.

The TPS55288 employs 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 TPS55288 also provides optional spread spectrum to minimize peak EMI.

The TPS55288 offers output over-voltage protection, average inductor current limit, cycle-by-cycle peak current limit and output short circuit protection. The TPS55288 also ensures safe operating with optional output current limit and hiccup-mode protection in sustained overload conditions.

The TPS55288 can use a small inductor and small capacitors with high switching frequency. It is available in 4.0-mm × 3.5-mm QFN package.
