Complete Current Share 10A DC/DC Power Module

ISL8200AM

The ISL8200AM 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

ISL8200AM, a few passive components and one VOUT 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? Parallel up to six ISL8200AM

modules to scale up to a 60A solution (see Figure 6 on

page 10).

The simplicity of the ISL8200AM is in its "Off The Shelf",

unassisted implementation versus a discrete implementation.

Patented current sharing in multi-phase operation greatly

reduces ripple currents, BOM cost and complexity. For

example, parallel 2 for 20A and up to 6 for 60A. The output

voltage can be precisely regulated to as low as 0.6V with ±1%

output voltage regulation over line, load, and temperature

variations.

The ISL8200AM’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.
