1_00 The S-85S1A Series introduces own distinctive low power consumption control and COT (Constant On-Time) control and features ultra low current consumption and fast transient response.
PWM / PFM switching control automatically switches to PFM control when under light load, and the IC operates at ultra low current consumption of 260 nA quiescent current.
The S-85S1A 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.
The S-85S1A Series can configure a step-down regulator only with a coil, an input capacitor, and an output capacitor.
By using external parts recommended in this datasheet, the occupancy area can be reduced to 2.
