SC4524B  
16V 2A Step-Down Switching Regulator  
POWER MANAGEMENT  
Features  
Description  
Wide input range: 3V to 16V  
2A Output Current  
200kHz to 2MHz Programmable Frequency  
Precision 1V Feedback Voltage  
Peak Current-Mode Control  
Cycle-by-Cycle Current Limiting  
Hiccup Overload Protection with Frequency Foldback  
Soft-Start and Enable  
Thermal Shutdown  
The SC4524B is a constant frequency peak current-mode  
step-down switching regulator capable of producing 2A  
output current from an input ranging from 3V to 16V. The  
switching frequency of the SC4524B is programmable  
up to 2MHz, allowing the use of small inductors and  
ceramic capacitors for miniaturization, and high input/  
output conversion ratio. The SC4524B is suitable for  
next generation XDSL modems, high-definition TVs and  
various point of load applications.  
Thermally Enhanced 8-pin SOIC Package  
Fully RoHS and WEEE compliant  
Peak current-mode PWM control employed in the  
SC4524B achieves fast transient response with simple loop  
compensation. Cycle-by-cycle current limiting and hiccup  
overload protection reduces power dissipation during  
output overload. Soft-start function reduces input start-  
up current and prevents the output from overshooting  
during power-up.  
Applications  
XDSL and Cable Modems  
Set Top Boxes  
Point of Load Applications  
CPE Equipment  
DSP Power Supplies  
LCD and Plasma TVs  
The SC4524B is available in SOIC-8 EDP package.
