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 7 on
page 10).
The simplicity of the ISL8200AM is in its "off-the-shelf",
unassisted implementation versus a discrete implementation.
Patented current sharing in multiphase 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 backside 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.
Features
• 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)
• Input voltage range +3V to +20V at 10A, current share up to
60A
• A single resistor sets VOUT from +0.6V to +6V
• Output overvoltage, overcurrent and over-temperature
protection and undervoltage indication
• RoHS compliant
Applications
• Servers, telecom and datacom applications
• Industrial and medical equipment
• Point of load regulation

PD1 Phase Thermal Pad Used for both the PHASE pin (Pin 16) and for heat removal connecting to heat dissipation layers using vias. Connect this pad
to a copper island on the PCB board with the same shape as the pad; this is electrically connected to PHASE Pin 16.
PD2 PVIN Thermal Pad Used for both the PVIN pin (Pin 17) and for heat removal connecting to heat dissipation layers using vias. Connect this pad
to a copper island on the PCB board with the same shape as the pad; this is electrically connected to PVIN Pin 17.
PD3 PGND Thermal Pad Used for both the PGND pin (Pin 18) and for heat removal connecting to heat dissipation layers using vias. Connect this pad
to a copper island on the PCB board with the same shape as the pad; this is electrically connected to PGND Pin 18.
PD4 VOUT Thermal Pad Used for both the VOUT pin (Pin 19) and for heat removal connecting to heat dissipation layers using vias. Connect this pad
to a copper island on the PCB board with the same shape as the pad; this is electrically connected to VOUT Pin 19.
