S-8590AA/8590AB/8591AA/8591AB Series www.ablic.com © ABLIC Inc., 2019-2021 18 V INPUT, 600 mA SYNCHRONOUS STEP-DOWN SWITCHING REGULATOR Rev.2.1_00 The S-8590/8591 Series is a step-down switching regulator developed using high withstand voltage CMOS process technologies. This IC has high maximum operation voltage of 18 V and maintains high-accuracy FB pin voltage at ±1.5%. As suitable packages for high-density mounting, such as small-sized HSNT-6(2025), are adopted, this IC contributes to miniaturization of electronic equipment. PWM control (S-8590 Series) or PWM / PFM switching control (S-8591 Series) can be selected as an option.
