ISL6277A
Multiphase PWM Regulator for AMD Fusion™ Mobile CPUs Using SVI 2.0
FN8322 Rev 2.00 December 4, 2015
The ISL6277A is fully compliant with AMD Fusion SVI 2.0 and provides a complete solution for microprocessor and graphics processor core power. The ISL6277A controller supports two Voltage Regulators (VRs) with three integrated gate drivers and two optional external drivers for maximum flexibility. The Core VR can be configured for 3-, 2-, or 1-phase operation while the Northbridge VR supports 2- or 1-phase configurations. The two VRs share a serial control bus to communicate with the AMD CPU and achieve lower cost and smaller board area compared with two-chip solutions.
The PWM modulator is based on Intersil’s Robust Ripple Regulator R3™ Technology.
