ISL8200M :New Power Module Solves the 5 Most Difficult Power Supply Challenges Complete Current Share 10A DC/DC Power Supply
The ISL8200M is a simple and easy to use high power, current-sharing DCDC power supply module for those power hungry DatacomTelecomServers. All you need is the ISL8200M, a few components and one VOUT setting resistor, RSET and you 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 current? Just current-share the ISL8200M to scale the solution up to 60A of output current by paralleling up to 6 modules.
The simplicity of the ISL8200M is in the part’s "Off The Shelf", unassisted implementation. Patented current balancing in multi-phase operation greatly reduces ripple currents, BOM cost and complexity.
The ISL8200M thermally enhanced, compact (15mmx15mmx2.2mm) QFN Package, operates without a heat sink, even at full load and over-temperature. The limited number of external components, lack of a heat dissipation layer, along with side access to all pins, reduces the PCB design to a component layer and a simple ground layer.
ISL8200M 主要特性:
• Complete Switch Mode Power Supply in One Package
• Programmable Phase Shift (1 to 6 phase) for Current Sharing Modules
• Patented Current Share Architecture Reduces Layout Sensitivity When Modules are Paralleled
• Low Profiles (2.2mm height)
• Input Voltage Range +3.0 V to +20V at 10A, Current Share up to 60A
• A Single Resistor Sets VOUT from +0.6V to +6V
• Output Overvoltage,Overcurrent and Over-...
