3 Description
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.
