ISL6445, Step-Down PWM Controller
DATASHEET 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 incorporate
ISL6445 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
