Scalable Point-of-Load (POL) offers design flexibility for a wide range of load-current requirements for modern day electronic loads. Combined with benefits derived from digital power management, the scalable digital POL simplifies and speeds design while offering a cost-effective solution. This white paper discusses general approach for scalable POL design and introduces the ISL68300 and ISL68301 digital PWM buck controllers from Renesas, highlighting their benefits for scalable POL designs.
