1.4MHz Dual, 180° Out-of-Phase, Step-Down PWM Controller

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.

Features

• Wide Input Supply Voltage Range

- 5.6V to 24V

- 4.5V to 5.6V

• Two Independently Programmable Output Voltages

• Switching Frequency . . . . . . . . . . . . . . . . . . . . . . .1.4MHz

• Out-of-Phase PWM Controller Operation

- Reduces Required Input Capacitance and Power Supply Induced Loads

• No External Current Sense Resistor

- Uses Lower MOSFET’s rDS(ON)

• Programmable Soft-Start

• Extensive Circuit Protection Functions

- PGOOD

- UVLO

- Overcurrent

- Over-temperature

- Independent Shutdown for Both PWMs

• Excellent Dynamic Response

- Voltage Feed-Forward with Current Mode Control

• Pb-Free (RoHS Compliant)

Applications

• Power Supplies with Two Outputs

• xDSL Modems/Routers

• DSP, ASIC, and FPGA Power Supplies

• Set-Top Boxes

• Dual Output Supplies for DSP, Memory, Logic, µP Core and I/O

• Telecom Systems
