ISL8200M Datasheet, PDF (1/23 Pages) Intersil Corporation – Complete Current Share 10A DC/DC Power Supply

Complete Current Share 10A DC/DC Power Supply
ISL8200M
The ISL8200M is a simple and easy to use high power,
current-sharing DC\DC power supply module for those
power hungry Datacom\Telecom\Servers. All you need
is the ISL8200M, a few components and one V_OUT
setting resistor, R_SET and you 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 current? Just current-share the ISL8200M
to scale the solution up to 60A of output current by
paralleling up to 6 modules.
The simplicity of the ISL8200M is in the part’s "Off The
Shelf", unassisted implementation. Patented current
balancing in multi-phase operation greatly reduces
ripple currents, BOM cost and complexity.
The ISL8200M thermally enhanced, compact
(15mmx15mmx2.2mm) QFN Package, operates
without a heat sink, even at full load and
over-temperature. The limited number of external
components, lack of a heat dissipation layer, along with
side access to all pins, reduces the PCB design to a
component layer and a simple ground layer.
