Complete Current Share 10A DC/DC Power Module

ISL8200M

The ISL8200M is a simple and easy to use high power,

current-sharing DC\DC power module for

Datacom\Telecom\FPGA power hungry applications. All

that is needed is the ISL8200M, a few passive

components and one V OUT setting resistor to have a

complete 10A design ready for market.

The ease of use virtually eliminates the design and

manufacturing risks while dramatically improving time

to market.

Need more output current? Just simply parallel up to six

ISL8200M modules to scale up to a 60A solution (see

Page 7, Figure 6).

The simplicity of the ISL8200M is in its "Off The Shelf",

unassisted implementation. Patented current sharing

in multi-phase operation greatly reduces ripple

currents, BOM cost and complexity.

The ISL8200M’s thermally enhanced, compact QFN

package, operates at full load and over-temperature,

without requiring forced air cooling. It's so thin it can

even fit on the back side of the PCB. Easy access to all

pins with few external components, reduces the PCB

design to a component layer and a simple ground

layer.
