3
)
reduces power system footprint by >40%
•
“Full Chip” V
•
I 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.
DESCRIPTION
The V
•
I Chip
TM
bus converter is a high efficiency (>95%) Sine
Amplitude Converter
TM
(SAC
TM
) operating from a 330 to 365
Vdc primary bus to deliver an isolated 41.25 – 45.63 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 BCM352F440T330A00 is 1/8, that capacitance
value can be reduced by a factor of 64x, resulting in savings of
board area, materials and total system cost.
The BCM352F440T330A00 is provided in a V
•
I Chip package
compatible with standard pick-and-place and surface mount
assembly processes. The V
•
I Chip package provides flexible
thermal management through its low junction-to-case and
junction-to-board thermal resistance. With high conversion
efficiency the BCM352F440T330A00 increases overall system
efficiency and lowers operating costs compared to
conventional approaches.
