Description

The TPS55285 is a fully integrated synchronous buck-boost converter that is optimized for converting battery voltage, USB Power Delivery (USB PD) or adaptor voltage into power supply rails. The TPS55285 integrates four 15mΩ MOSFETs to provide a high efficiency and small size solution.

The TPS55285 has a wide input voltage range from 2.4V (3.0V rising) to 22V and is capable of outputting 0.8V to 15V voltage with 10mV step to support a variety of applications. The TPS55285 features 8A average inductor current limit and supplies up to 7A output current in buck mode. In boost mode, it is able to deliver 60W from 12V input or 30W from 5V input.

Through the I2C interface, the output voltage of the TPS55285 is programmed dynamically. The default output voltage is 5V when the device is enabled. The I2C interface allows for configuration of slew rate of the output voltage change, switching frequency, forced PWM mode operation.

The TPS55285 offers input and output overvoltage protection, average inductor current limit, cycle-by-cycle peak current limit and output short circuit protection. The TPS55285 also allows for safe operating with output current limit without external output current sense resistor and hiccup mode protection in sustained overload conditions.

The TPS55285 allows the use of small inductor and capacitor with high switching frequency. The TPS55285 is available in 2.5mm × 3.5mm QFN package.
