VIN = 48V (38 – 55V)
POUT= up to 300W
K = 1
• High efficiency (>96%) reduces system
power consumption
VOUT = 48.0V (38.0 – 55.0V)
(no load)
• High power density (>1022W/in3)
Description
reduces power system footprint by >40%
• Contains built-in protection features:
n Undervoltage
The VI Chip® bus converter is a high efficiency (>96%) Sine
Amplitude Converter™ (SAC™) operating from a 38 to 55VDC
primary bus to deliver an isolated, ratiometric output voltage from
38.0 to 55.0VDC. The Sine Amplitude Converter offers a low AC
impedance beyond the bandwidth of most downstream regulators;
therefore capacitance normally at the load can be located at the
input to the Sine Amplitude Converter. Since the transformation
ratio of the BCM48Bx480y300A00 is 1, the capacitance value can
be reduced by a factor of 1x, resulting in savings of board area,
materials and total system cost.
n Overvoltage Lockout
n Overcurrent Protection
n Short circuit Protection
n Overtemperature Protection
• Provides enable/disable control,
internal temperature monitoring
• Can be paralleled to create multi-kW arrays
The BCM48BF480y300A00 is provided in a VI Chip package
compatible with standard pick-and-place and surface mount
assembly processes. The co-molded VI Chip package provides
enhanced thermal management due to a large thermal interface
area and superior thermal conductivity. The high conversion
efficiency of the BCM48Bx480y300A00 increases overall
system efficiency and lowers operating costs compared to
conventional approaches.
