SC2447 产品详情

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.

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 Pre-Bias Output
◆ Tri-State PWM Output during Shutdown
◆ Programmable Frequency Up to 1MHz Per Phase
◆ External Synchronization
◆ TSSOP-28 Lead-free Package. Fully WEEE and RoHS Compliant

Applications
◆ Telecommunication Power Supplies
◆ DDR Memory Power Supplies
◆ Graphic Power Supplies
◆ Servers and Base Stations
