RENESAS PMBus compliant, fully digital dc-dc controllers provide single output point-of-load (POL) conversions for FPGAs, DSPs, ASICs, network processors and general purpose system rails. Model ISL68300 with integrated MOSFET drivers and ISL68301 with PWM output simplify designing power supplies for data center, wired and wireless communications and factory automation equipment. ISL68300 can drive discrete external MOSFETs directly, while ISL68301 pairs with firm’s smart power stages or DrMOS power stages to create a complete voltage regulator solution. Both devices provide a high-speed current share bus that parallels up to eight controllers in an 8-phase 240A+ current share configuration.
