ISL8200AM

Complete Current Share 10A DC/DC Power Module

Product Status: Mass Production

OVERVIEW

The ISL8200AM is a simple and easy to use high power, current-sharing DC/DC power module for datacom, telecom, and 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 practically eliminates design and manufacturing risks while dramatically improving time to market.

Parallel up to six ISL8200AM modules to scale up to a 60A solution for more output current.

The simplicity of the ISL8200AM is in its “off-the-shelf”, unassisted implementation compared to a discrete implementation. Patented current sharing in multiphase operation greatly reduces ripple currents, BOM cost, and complexity. For example, parallel two devices for 20A of current and up to six for 60A of current. 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. The package is 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.

KEY 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
