Description
AI
The TPS55289-Q1 is a synchronous buck-boost converter that is optimized for converting battery voltage or adapter voltage into power supply rails. The TPS55289-Q1 integrates four MOSFET switches providing a compact solution for USB Power Delivery (USB PD) application.
The TPS55289-Q1 has up to 36V input voltage capability. Through the I2C interface, the output voltage of the TPS55289-Q1 can be programmed from 0.8V to 22V with 10mV step. When working in boost mode, it can deliver 60W from a 12V input voltage. It is capable of delivering 45W from 9V input voltage.
The TPS55289-Q1 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 TPS55289-Q1 also provides optional spread spectrum to minimize peak EMI.
The TPS55289-Q1 offers output over-voltage protection, average inductor current limit, cycle-by-cycle peak current limit and output short circuit protection. The TPS55289-Q1 also ensures safe operating with optional output current limit and hiccup-mode protection in sustained overload conditions.
The TPS55289-Q1 can use a small inductor and small capacitors with high switching frequency. It is available in a 3.0mm × 5.0mm QFN package.
