SC4524  
Programmable Frequency, 2A Output  
30V Step-Down Switching Regulator  
POWER MANAGEMENT  
Description  
Features  
The SC4524 is an adjustable frequency peak current- Up to 1.5 MHz Programmable Switching Frequency  
mode step-down switching regulator with an integrated  
2.3A, 30V switch. The SC4524 can be programmed up  
to 1.5MHz. This allows the use of small inductor and  
ceramic capacitors, resulting in very compact power  
supplies. The SC4524 is suitable for next generation XDSL  
modems, set-top boxes and point of load applications.  
2.3A Integrated Switch  
Wide Input Voltage Range 2.8V to 30V  
Peak Current-Mode Control with Cycle-by-Cycle  
Current Limiting  
Hiccup Overload Protection  
Soft-Start and Enable  
Thermal Shutdown  
Thermally Enhanced 8-Pin SOIC Package  
Fully WEEE and RoHS Compliant  
The SC4524 uses peak current-mode PWM control for  
ease of compensation. Cycle-by-cycle current limit and  
hiccup overload protection reduce power dissipation  
during overload. Combined soft start and enable pin not  
only eliminates output start up overshoot but also allows  
power sequencing.  
The SC4524 is available in SOIC-8 EDP package.
