APPLICATIONS  
Note  
External divider network needed  
• Point of load regulation for low-power processors,  
network processors, DSPs, FPGAs, and ASICs  
• Low voltage, distributed power architectures with 5 V or  
12 V, or 24 V rails  
DESCRIPTION  
The SiC401, SiC402, and SiC403 are high frequency  
voltage-mode constant-on-time (CM-COT) synchronous  
buck regulators with integrated high-side and low-side  
power MOSFETs. The SiC403 is capable of 6 A continuous  
current, the SiC402 is capable of 10 A and the SiC401 15 A.  
These regulators produce an adjustable output voltage  
which in standard setup can output 5 V down to 0.6 V  
and with the VOUT divider network 75 % of VIN down to  
0.6 V to accommodate a variety of applications, including  
computing, consumer electronics, telecom, and industrial.  
• Computing, broadband, networking, LAN / WAN, optical,  
test, and measurement  
• A / V, high density cards, storage, DSL, STB, DVR, DTV,  
industrial PC  
ORDERING INFORMATION

15 A  
The CM-COT architecture delivers ultra-fast transient  
response with minimum output capacitance and tight ripple  
regulation at very light load. The parts are stable with any  
capacitor type and no ESR network is required for loop  
stability. The regulator integrates a full protection feature  
set, it also has UVLO for the input rail and an internal  
soft-start.  
SiC401DB-HC  
Notes  
LC - low current inductor, HC - high current inductor  
The only difference between HC and LC board is the O / P  
inductor size  
The SiC40X family is available in lead (Pb)-free power  
enhanced 5 mm x 5 mm MLP55-32L package.
