TPS552892/TPS552892-Q1 Buck-Boost Converter

The Texas Instruments TPS552892/TPS552892-Q1 Synchronous Buck-Boost Converter is optimised for converting battery or adapter voltage into power supply rails. The TPS552892/TPS552892-Q1 integrates four MOSFET switches, providing a compact solution for various applications. The TPS552892/TPS552892-Q1 has up to 36V input voltage capability. The TPS552892/TPS552892-Q1 can deliver 60W from a 12V input when working in boost mode. It is capable of providing 45W from a 9V input voltage. The TPS552892/TPS552892-Q1 employs an average current-mode control scheme. The switching frequency is programmable from 200kHz to 2.2MHz by means of an external resistor, and can be synchronised with an external clock. The TPS552892/TPS552892-Q1 also provides an optional spread spectrum to minimise peak EMI.
