PMP23637
Compact dual-phase multi-cell battery charger reference design with dual FETs
PMP23637
概述
This reference design features the BQ25770/ BQ25773, 2-to-5 cell NVDC quasi-dual-phase buck- boost battery charge controller in a high-density design for notebook PC and portable applications. The dual-phase topology utilizes two small inductors and two half bridge dual-FETs, thus minimizing hot spots and spreading heat across the board. The topology also supports a 2-to-5 cell battery and accepts a wide input range including USB adapter, high voltage USB-C® Power Delivery (PD) sources, and traditional adapters.
