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 solution. The TPS61287 has wide input voltage range from 2.0V to 23V and the output voltage covers up to 25V with 20A switching valley current capablity.
The TPS61287 uses adaptive constant on-time valley current control topology to regulate the output voltage. Under moderate to heavy load condition, the TPS61287 operates in pulse width modulation (PWM) mode. There are two optional modes in light load by configuring the MODE pin: Auto PFM mode to improve light-load efficiency and Forced PWM to avoid audible noise and other problems caused by low switching frequency.
The TPS61287 supports stackable multi-phase operation. Up to 4pcs TPS61287 can be configured for multi-phase operation at same switching frequency to support higher power and input current balancing.
The TPS61287 offers a very small solution size with 2.5mm x 3.0mm VQFN HotRod™ Lite package with minimal external components.
