FEATURES

DESCRIPTION

The V•I Chip^TMBus Converter is a high efficiency (>95%) Sine

Amplitude Converter^TM(SAC^TM) operating from a 38 to 55 Vdc

primary bus to deliver an isolated 12 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 12 V

regulator can be located at the input to the SAC. Since the

K factor of the BCM48BH120T120A00 is 1/4, that capacitance

value can be reduced by a factor of 16x, resulting in savings of

board area, materials and total system cost.

• 48 Vdc – 12 Vdc 120 W Bus Converter

• High efficiency (>95%) reduces system power

consumption

• High power density (801 W/in³) reduces power system

footprint by >50%

•

• “Half Chip” V I Chip package enables surface mount,

low impedance interconnect to system board

• Contains built-in protection features: undervoltage,

overvoltage lockout, over current protection, short

circuit protection, overtemperature protection.

The BCM48BH120T120A00 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 BCM48BH120T120A00 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

• Less than 50°C temperature rise at full load in typical

applications
