ISL6445規(guī)格書詳情
1.4MHz Dual, 180° Out-of-Phase, Step-Down PWM Controller
The ISL6445 is a high-performance, dual-output PWM 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 180o out-of-phase reducing the RMS input current and ripple voltage.
