Single-Phase Buck PWM Controller with Integrated MOSFET Drivers for Intel VR11 and AMD Applications
●The ISL6314 single-phase PWM control IC provides a precision voltage regulation system for advanced microprocessors. This controller IC maintains the same features as the multi-phase product family, but reduces the output to a single-phase, for lower current systems. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution.
