Introduction

AI Translation

The S-19902/19903 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. Since the S-19903 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-19902/19903 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. ABLIC Inc. offers FIT rate calculated based on actual customer usage conditions in order to support customer functional safety design.
