ISL6441 Datasheet Step-down Pwm And Single Linear Controller

Manufacturer: Renesas

Overview: DATASHEET ISL6441 1.4MHz Dual, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller FN9197 Rev 3.00 May 26, 2009 The ISL6441 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 RMS input current and ripple voltage.

Key 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 input (SD1 and SD2). A single PGOOD signal is issued when soft-start is complete on both PWM controllers and their outputs are within 10% of the set p.
