Complete Current Share 10A DC/DC Power Module
ISL8200AMM
The ISL8200AMMREP 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 ISL8200AMMREP, 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? Parallel up to six ISL8200AMMREP
modules to scale up to a 60A solution (see Figure 6 on
page 10).
The simplicity of the ISL8200AMMREP 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 ISL8200AMMREP’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.
