Quad DC/DC µModule Regulator with

Configurable Dual 12A, Dual 5A Output Array

FEATURES

DESCRIPTION

Quad Output Step-Down µModule^®Regulator with

Dual 12A and Dual 5A Output

ꢁhe LꢁM^®467± is a quad DC/DC step-down µModule

(micromodule) regulator offering dual ±2A and dual ꢀA

output. Included in the package are the switching control-

lers, power FEꢁs, inductors and support components.

Operating over an input voltage range of 3.±V to 20V, the

LꢁM467± supports an output voltage range of 0.6V to

3.3V for two ±2A channels and 0.6V to ꢀ.ꢀV for two ꢀA

channels, each set by a single external resistor. Only bulk

input and output capacitors are needed.

Wide Input Voltage Range: 3.1V to 20V

Dual 12A DC Output from 0.6V to 3.3V

Dual 5A DC Output from 0.6V to 5.5V

Up to 7W Power Dissipation (T = 60°C, 200LFM,

No Heat Sink)

±±.ꢀ5 ꢁotal Output Voltage Regulation

Dual Differential Sensing Amplifier

Current Mode Control, Fast ꢁransient Response

Parallelable for Higher Output Current

Selectable Burst Mode^®Operation

Output Voltage ꢁracking

Internal ꢁemperature Sensing Diode Output

External Frequency Synchronization

Overvoltage, Current and ꢁemperature Protection

9.ꢀmm × ±6mm × 4.72mm BGA Package

Fault protection features include overvoltage, overcurrent

and overtemperature protection. ꢁhe LꢁM467± is offered

in 9.ꢀmm × ±6mm × 4.72mm BGA package.
