描述 Description

The SC2441 is a high-frequency triple output switching regulator controller. It consists of a dual out-of-phase synchronous step-down PWM controller with high-current output gate drives and a 1.7A integrated step-up switching regulator.

特性 Features

2-Phase Synchronous step-down controllers

◆ 2-Phase Synchronous Continuous Conduction Mode For High Efficiency Step-down Converters

◆ Out of Phase Operation For Low Input Current Ripples

◆ Operates Up To 1MHz Per Channel

◆ Configurable Dual Outputs Or 2-Phase Single Output Operation with Peak Current Mode Control

◆ Excellent Current Sharing Between Phases

◆ Wide Input Voltage Range: 1.8V to 15V

◆ Duty Cycle Up to 90

◆ 0.5V Feedback Voltages For Low-Voltage Outputs

◆ Precision 50mV Current-Limit Threshold

◆ Patented Combi-sense Technique for High SNR of Current-Sensing

◆ Individual Soft-Start, Overload Shutdown and Enable

Step-up Regulator

◆ Wide Input Voltage Range: 1.8V to 15V

◆ Operates At Twice The Individual Channel Frequency Of The Buck Controllers

◆ 0.23V VCESAT Switch at 1A

◆ Fixed Frequency with Current-Mode Control

Common Features

◆ External Synchronization

◆ Industrial Temperature Range

Applications

◆ Low Voltage Distributed DC-DC Converters

◆ Telecommunication Power Supplies

◆ Servers and base stations
