ISL6443 Step-Down PWM and Single Linear Controller

NOT RECOMMENDED FOR NEW DESIGNS USE ISL6443A DATASHEET ISL6443 300kHz Dual, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller FN9044 Rev 2.00 Aug 9, 2006 The ISL6443 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 180° out of phase reducing the.

ISL6443 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. Each PWM has an independent logic-level shutdown
