The BD99950MUV is a high-efficiency, synchronous Narrow VDC system voltage regulator and battery charger controller. It has two charge pumps which separately drive N-channel MOSFETs for automatic system power source selection. Charge voltage, charge current, AC adapter current and minimum system voltage can be programmed through SMBus. With a small inductor, PWM switching frequency can also be programmed by SMBus up to 1.2MHz.

特點(diǎn)：
N-channel MOSFETs available for Battery or
Adapter Selection via Internal Charge Pumps
Fast DPM Transient Response under Turbo Mode (<100μs)
Linear Mode Trickle Charge via BGATE Charge Pump
Low Operating Current BGATE Charge Pump at 17μA (typical)
