Ablic S-85V1A

5.5 V Input, 200 mA Synchronous Step-down Switching Regulator with 10 μA Quiescent Current S-85V1A Series

Overview

TopologyBuck Converter
Input voltage2.2-5.5 V
Output 11.8 V / 0.2 A
IC revision1.2

Description

The S-85V1A Series is a step-down switching regulator which features high efficiency and fast transient response.Since PWM / PFM switching control automatically switches to PFM control when under light load, high efficiency is realized. This IC is suitable for mobile devices and battery powered devices due to introduction of own distinctive COT (Constant On-Time) control.Also, high-density mounting is realized by adopting super-small, thin SNT-6A package. Therefore, the occupancy area including a coil, an input capacitor and an output capacitor can be reduced to 2.0 mm × 4.5 mm = 9.0 mm2, and it contributes to miniaturization of electronic equipment.
