DC-DC Cntrlr Dual-OUT Step Down 1100kHz 24Pin TSSOP T/R
Description
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. Both converters are synchronized to prevent beat frequencies. The dual buck converters are also operated out of phase reducing input ripple, allowing for fewer input capacitors.
Features
♦ Dual output controller
♦ Asynchronous start up mode
♦ Power up sequencing to prevent latch-ups
♦ Out of phase operation for low input ripple
♦ Over current protection
♦ Output down to 0.75V
♦ 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 1.1MHz
♦ Two synchronous bucks for high efficiency at high current
♦ –40 to +125 Deg C operating temperature
♦ Small package TSSOP-24
♦ 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.
