The TPS55287 is a synchronous buck-boost converter that is optimized for converting battery voltage or adapter voltage into power supply rails. The TPS55287 integrates four MOSFET switches, providing a compact solution for USB power delivery (USB PD) application.
The TPS55287 has up to 36V input voltage capability. Through the I2C interface, the output voltage of the TPS55287 can be programmed from 0.8V to 22V with 10mV step. When working in boost mode, the device can deliver 35W from a 12V input. It is capable of delivering 25W from 9V input voltage.
The TPS55287 employs an average current-mode control scheme. The switching frequency is programmable from 200kHz to 2.2MHz by an external resistor and can be synchronized to an external clock. The TPS55287 also provides optional spread spectrum to minimize peak EMI.
The TPS55287 offers output overvoltage protection, average inductor current limit, cycle-by-cycle peak current limit, and output short circuit protection. The TPS55287 also makes sure it safely operates with optional output current limit and hiccup-mode protection in sustained overload conditions.
The TPS55287 can use a small inductor and small capacitors with high switching frequency. It is available in a 3.0mm × 5.0mm QFN package.
