The S-8580/8581 Series is a step-down switching regulator developed using high withstand voltage CMOS process technologies. This IC has high maximum operation voltage of 36 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-8580 Series) or PWM / PFM switching control (S-8581 Series) can be selected as an option.Since the S-8581 Series, which features PWM / PFM switching control, operates with PWM control under heavy load and automatically switches to PFM control under light load, it achieves high-efficiency operation in accordance with the device's status.Furthermore, our distinctive PWM / PFM switching control technology suppresses the ripple voltage to be generated in VOUT while PFM control is in operation.Since the S-8580/8581 Series has the built-in synchronous circuit, it achieves high efficiency easier compared with conventional step-down switching regulators.In addition, it has the built-in overcurrent protection circuit which protects the IC and coils from excessive load current as well as a thermal shutdown circuit which prevents damage from heat generation.
