TPS552872/TPS552872-Q1 Buck-Boost Converter

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.
