TPS552892QWRYQRQ1

The TPS551892-Q1 is a synchronous buck-boost converter that is optimized for converting battery voltage or adapter voltage into power supply rails. The TPS551892-Q1 integrates four MOSFET switches providing a compact solution for a variety of applications. The TPS551892-Q1 has up to 27V input voltage capability. When working in boost mode, the TPS551892-Q1 can deliver 60W from a 12V input. It is capable of delivering 45W from 9V input voltage. The TPS551892-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 TPS551892-Q1 also provides optional spread spectrum to minimize peak EMI. The TPS551892-Q1 offers output over - voltage protection, average inductor current limit, cycle - by - cycle peak current limit, output short circuit protection. The TPS551892-Q1 also ensures safe operating with optional output current limit and hiccup - mode protection in sustained overload conditions. The TPS551892-Q1 can use a small inductor and small capacitors with high switching frequency. It is available in a 3.0mm×5.0mm QFN package.
