More Information

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.
