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.
