3 Description

The BQ25730 is a synchronous NVDC buck-boost

battery charge controller to charge a 1- to 5-cell

battery from a wide range of input sources including

USB adapter, high voltage USB-C Power Delivery

(PD) sources, and traditional adapters. It offers a low

component count, high efficiency solution for space

constrained, 1- to 5-cell battery charging applications.

The Narrow VDC buck-boost architecture avoid direct

power path from input source to system voltage

which implements wide input voltage range and

narrow system voltage range at same time. Narrow

system voltage range is valuable for faster battery

supplement and lower MOSFET rating for next stage

converter.
