SC4518H  
600kHz, 2A Step-Down  
Switching Regulator  
POWER MANAGEMENT  
Features  
Description  
The SC4518H is a current mode switching regulator with  
an integrated switch, operating at 600kHz with separate  
sync and enable functions. The integrated switch allows  
for cost effective low power solutions (peak switch current  
2 amps). The sync function allows customers to  
synchronize to a faster clock in order to avoid frequency  
beating in noise sensitive applications. High frequency  
of operation allows for very small passive components.  
Current mode operation allows for fast dynamic response  
and instantaneous duty cycle adjustment as the input  
varies (ideal for CPE applications where the input is a  
wall plug power).  
‹ Wide operating voltage range: 4.4V to 24V  
‹ Integrated 2 Amp switch  
‹ 600kHz frequency of operation  
‹ Current mode controller  
‹ Synchronizable to higher frequency up to 1.2MHz  
‹ Precision enable threshold  
‹ SO-8 EDP package. Lead free product, fully WEEE  
and RoHS compliant  
Applications  
‹ XDSL modems  
‹ CPE equipment  
‹ DC-DC point of load applications  
‹ Portable equipment  
The low shutdown current makes it ideal for portable  
applications where battery life is important.  
The SC4518H is a 600kHz switching regulator  
synchronizable to a faster frequency from 750kHz to  
1.2MHz.
