Sine Amplitude Converter™ (SAC™)  
FEATURES  
DESCRIPTION  
The VI Chip® bus converter is a high efficiency (>95%) Sine Am-  
plitude Converter™ (SAC™) operating from a 330 to 365 Vdc  
primary bus to deliver an isolated 11.79 – 13.04 V nominal,  
unregulated secondary. The SAC offers a low AC impedance  
beyond the bandwidth of most downstream regulators,  
meaning that input capacitance normally located at the input  
of a regulator can be located at the input to the SAC. Since the  
K factor of the BCM352F125T300A00 is 1/28, that capacitance  
value can be reduced by a factor of 784x, resulting in savings of  
board area, materials and total system cost.  
352 Vdc – 12.5 Vdc 300 W Bus Converter  
High efficiency (>95%) reduces system power  
consumption  
High power density (>1000 W/in3)  
reduces power system footprint by >40%  
“Full Chip” VI Chip® package enables surface mount,  
low impedance interconnect to system board  
Contains built-in protection features: undervoltage,  
overvoltage lockout, overcurrent protection, short  
circuit protection, overtemperature protection.  
The BCM352F125T300A00 is provided in a VI Chip package  
compatible with standard pick-and-place and surface mount  
assembly processes. The VI Chip package provides flexible ther-  
mal management through its low junction-to-case and junc-  
tion-to-board thermal resistance. With high conversion  
efficiency the BCM352F125T300A00 increases overall system  
efficiency and lowers operating costs compared to  
conventional approaches.  
Provides enable/disable control, internal temperature  
monitoring  
ZVS/ZCS Resonant Sine Amplitude Converter topology  
Can be paralleled to create multi-kW arrays
