 Description |
|
|
The ISL6315 two-phase PWM control IC provides a precision voltage regulation system for advanced loads up to 60A to 80A. Multiphase power conversion is a marked departure from single phase converter configurations employed to satisfy the increasing current demands of modern microprocessors and other electronic circuits. By distributing the power and load current, implementation of multiphase converters utilize smaller and lower cost transistors with fewer input and output capacitors. These reductions accrue from the higher effective conversion frequency with higher frequency ripple current due to the phase interleaving process of this topology.
Outstanding features of this controller IC include programmable VID codes compatible with Intel VRM9, VRM10, as well as AMD’s Hammer microprocessors, along with a system regulation accuracy of ±1%. The ISL6315, though, does not intrinsically allow for load-line regulation (no droop).
Important features of this controller IC include a set of sophisticated overvoltage and overcurrent protection. Overvoltage results in the converter turning the lower MOSFETs ON to clamp the rising output voltage and protect the microprocessor. Like other Intersil multiphase controllers, the ISL6315 uses cost and space-saving rDS(ON) sensing for channel current balance and overcurrent protection. Channel current balancing is automatic and accurate with the integrated current-balance control system. Overcurrent protection can be tailored to any application with no need for additional parts. These features provide intelligent protection for modern power systems. |
