S-19914/15 A/B
Describe: The S-19914/19915 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%. It has a built-in spread spectrum clock generation circuit capable of reducing conductive noise and emission noise during PWM operation. As suitable packages for high-density mounting, such as small-sized HSNT-8(2030), are adopted, this IC contributes to miniaturization of electronic equipment. Since the S-19914/19915 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.
