SC2447 - Dual-Phase Single or Two Output Synchronous Step-Down Controller

General Description

The SC2447 is a versatile high-frequency dual phase PWM step-down controller optimized for Philips and Renesas DrMOSTM.

Both phases are capable of sourcing or sinking load currents, making the SC2447 suitable for networking system power and DDR applications.

Key Features

  • 2-Phase Step-down Controller optimized for Philips or Renesas DrMOSTM Out of Phase Operation for Low Input Current Ripple Outputs Source and Sink Current Fixed Frequency Peak Current-Mode Control Lossless Inductor DCR Current Sensing Optional Resistor Current-Sensing for Precise Current-Limit Dual 30A Outputs or 2-Phase 60A Single Output Operation Wide Input Voltage Range: 4.65V to 15V Individual Closed-Loop Soft-Start, Overload Shutdown Timer and Enable Output Voltage as Low as 0.5V Starts into.

Dual-Phase, Single or Dual Output www.DataSheet4U.com Synchronous Step-Down Controller POWER MANAGEMENT Description The SC2447 is a versatile high-frequency dual phase PWM step-down controller optimized for Philips and Renesas DrMOSTM. Both phases are capable of sourcing or sinking load currents, making the SC2447 suitable for networking system power and DDR applications. The SC2447 employs fixed frequency, continuous-conduction peak current-mode control for easy compensation and fast transient response. The SC2447 can be used to generate two independent outputs (up to 30A per output) or a single 60A output with shared phase current. The PWM signals are 180° out of phase to minimize input/output ripple.
