5.5 V INPUT, 200 mA SYNCHRONOUS STEP-DOWN SWITCHING REGULATOR WITH 260 nA QUIESCENT CURRENT
Rev.1.3_01
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.
