BCM^®Bus Converter

BCM48Bx120y120B00

NRTL US

Isolated Fixed Ratio DC-DC Converter

Features & Beneﬁts

Product Ratings

• 48V_DC– 12V_DC120W Bus Converter

V_IN= 48V (38 – 55V)

P_OUT= up to 120W

K = 1/4

• High efﬁciency (>95%) reduces

system power consumption

V_OUT= 12V (9.5 – 13.75V)

(no load)

• High power density (801W/in³) reduces

power system footprint by >50%

Description

• “Half Chip” VI Chip^®package enables surface mount,

low impedance interconnect to system board

The VI Chip^®Bus Converter is a high efﬁciency (>95%) Sine

Amplitude ConverterTM (SAC^TM) operating from a 38 to 55V_DC

primary bus to deliver an isolated ratiometric output voltage from

9.5 to 13.75V_DC. 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 12V regulator

can be located at the input to the SAC. Since the K factor of

the BCM48Bx120y120B00 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.

• Contains built-in protection features against:

nꢀUndervoltage

nꢀOvervoltage

nꢀOvercurrent

nꢀShort Circuit

nꢀOvertemperature

• Provides enable/disable control,

internal temperature monitoring

The BCM48BH120y120B00 is provided in a VI Chip package

compatible with standard pick-and-place and surface mount

assembly processes. The VI Chip package provides ﬂexible thermal

management through its low junction-to-case and junction-to-

board thermal resistance. With high conversion efﬁciency the

BCM48Bx120y120B00 increases overall system efﬁciency and

lowers operating costs compared to conventional approaches.

• ZVS/ZCS Resonant Sine Amplitude Converter topology

• Less than 50°C temperature rise at full load
