Texas Instruments TPS552872/TPS552872-Q1 Fully Integrated Buck-Boost Converter is optimized for converting battery or adapter voltage into power supply rails. The TPS552872/TPS552872-Q1 integrates four MOSFET switches, providing a compact solution for various applications. The TPS552872/TPS552872-Q1 has up to 36V input voltage capability. When working in boost mode, the TPS552872/TPS552872-Q1 can deliver 30W from a 12V input. It is capable of providing 25W from a 9V input voltage.
The TPS552872/TPS552872-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 TPS552872/TPS552872-Q1 also provides an optional spread spectrum to minimize peak EMI.
The TPS552872/TPS552872-Q1 offers output over-voltage protection, average inductor current limit, cycle-by-cycle peak current limit, and output short circuit protection. The TPS552872/TPS552872-Q1 also ensures safe operation with an optional output current limit and hiccup-mode protection in sustained overload conditions.
The Texas Instruments TPS552872/TPS552872-Q1 can use a small inductor and small capacitors with high switching frequency. It is available in a 3.0mm × 5.0mm QFN package. The TPS552872-Q1 devices are AEC-Q100 qualified for automotive applications.
