MAX8630W Description
Features ♦ 93% Max/85% Avg. By utilizing adaptive 1x/1.5x charge-pump modes and very low-dropout current regulators, they achieve high efficiency over the full 1-cell Li+ battery input voltage range. The 1MHz fixed-frequency switching allows for tiny external ponents, and the regulation scheme is optimized to ensure low EMI and low input ripple.
