Description: Dual-Phase Single or Two Output Synchronous Step-Down Controller

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 3

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
