Complete Current Share 10A DC/DC Power Module
ISL8200AM
Features
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.
• Complete Switch Mode Power Supply in One Package
• Patented Current Share Architecture Reduces Layout
Sensitivity when Modules are Paralleled
• Programmable Phase Shift (1 to 6 Phase)
• Extremely Low Profile (2.2mm Height)
The ease of use virtually eliminates the design and
manufacturing risks while dramatically improving time to
market.
• Input Voltage Range +3.0V to +20V at 10A, Current Share
up to 60A
• A Single Resistor Sets V
OUT
from +0.6V to +6V
Need more output current? Parallel up to six ISL8200AM
modules to scale up to a 60A solution (see Figure 6 on
page 10).
• Output Overvoltage, Overcurrent and Over-Temperature
Protection and Undervoltage Indication
• RoHS Compliant
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.
Applications
• Servers, Telecom and Datacom Applications
• Industrial and Medical Equipment
• Point of Load Regulation

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.
