Ablic S-85M0A

Description

The S-85M0A Series introduces own distinctive low power consumption control and COT (Constant On-Time) control,features ultra low current consumption (260 nA quiescent current) and fast transient response, operates at PFM control.The S-85M0A Series realizes high efficiency in a wide range of load current consumption and provides strong support for extended period operation of mobile devices and wearable devices which are equipped with compact batteries.In addition, WLP-6L package suitable for high-density mounting is adopted, it contributes to miniaturization of electronic equipment. By using external parts recommended in this datasheet, the occupancy area can be reduced to 1.6 mm × 2.7 mm = 4.3 mm2.Since the S-85M0A Series suppressing EMI emission minimally, allows for high efficiency, it is adequate for applications such as wireless communication, GPS and other noise-affected devices.
