1.1 Introduction of TPS61287

The TPS61287 is a high-power density, synchronous boost converter that integrates high side synchronous rectifier MOSFET and uses an external low side MOSFET to provide a high efficiency and small size. The TPS61287 has wide input voltage range from 2V to 23V and the output voltage covers up to 25V with 20A switching valley current capability.

The TPS61287 uses adaptive constant on-time valley current control topology to regulate the output voltage and supports stackable multiphase operation. Up to four pieces of TPS61287 can be configured for multi-phase operation at the same switching frequency to support higher power and input current balancing.
