ISL6445 Datasheet Step-down Pwm Controller

Manufacturer: Renesas

Overview: 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.

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 point. Thermal shut.
