The TPS552872-Q1 is a synchronous buck-boost converter that is optimized for converting battery voltage or adapter voltage into power supply rails. The TPS552872-Q1 integrates four MOSFET switches providing a compact solution for a variety of applications. The TPS552872-Q1 has up to 36V input voltage capability. When working in boost mode, the TPS552872-Q1 can deliver 30 W from a 12-V input. It is capable of delivering 25 W from 9-V input voltage.
The TPS552872-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 TPS552872-Q1 also provides optional spread spectrum to minimize peak EMI.
The TPS552872-Q1 offers output over-voltage protection, average inductor current limit, cycle-by-cycle peak current limit, output short circuit protection. The TPS552872-Q1 also ensures safe operating with optional output current limit and hiccup-mode protection in sustained overload conditions.
The TPS552872-Q1 can use a small inductor and small capacitors with high switching frequency. It is available in a 3.0-mm × 5.0-mm QFN package.
