This battery charger reference design is designed for a 5 to 24-VIN, 240-W power tool that features BQ25731 one- to five-cell NVDC buck-boost battery charge controller. This is a high power, high efficiency and high density design. PMP22805 delivers 240 W with 98% efficiency and fits in a compact 1.08 inch x 1.68 inch (27.4 mm x 42.7 mm) form factor. The USB On-The-Go (OTG) capability makes it a power bank. It is ideal for power tools where high power, high efficiency and high density are top priorities. This reference design supports 1 to 5S battery and accepts a wide-input range such as USB Type-C® PD interface.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
