ISL6445
1.4MHz Dual, 180° Out-of-Phase, Step-Down PWM Controller
FN9230 Rev 1.00 Jun 3, 2008
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.
The ISL6445 incorporates several protection features. An adjustable overcurrent protection circuit monitors the output current by sensing the voltage drop across the lower MOSFET. Hiccup mode overcurrent operation protects the DC/DC components from damage during output overload/short circuit conditions.
