SC2442, High-Performance Wide Input Range Dual Synchronous Buck Controller

加入关注列表

SC2442 and SC2442H are high performance dual buck converter controllers that can be configured for a variety of synchronous buck applications where efficiency is most important.

Features


  • Dual output controller
  • Asynchronous start-up mode
  • Power-up sequencing to prevent latch-up
  • Out-of-phase operation for low-input ripple
  • Over-current protection
  • Output down to 0.75 V
  • Wide input range, 4.75 to 30V for SC2442 and 4.75 to 36V for SC2442H
  • Vcc regulator with external PNP transistor
  • Programmable clock frequency up to 1 MHz
  • Two synchronous bucks for high efficiency at high current
  • -40°C to +125°C operating temperature
  • Small TSSOP-24 package
  • Fully WEEE and RoHS Compliant

Applications


  • Point-of-load converter applications
  • DSL applications with multiple output voltages
  • Power management for mixed-signal applications
  • Cable modems and set-top boxes
