ISL6443A规格书详情
300kHz Dual, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller
The ISL6443A is a high-performance, triple-output controller optimized for converting wall adapter, battery or network intermediate bus DC input supplies into the system supply voltages required for a wide variety of applications. Each output is adjustable down to 0.8V. The two PWMs are synchronized at 180° out-of-phase, thus reducing the RMS input current and ripple voltage.
