A7531 Overview
FEATURES A7531 series are CMOS-based PFM step-up DC-DC Deliver 500mA at 4.0V output voltage with 2V Controller with low supply current and high output voltage accuracy. Quiescent current drawn from power source is as low as 6uA. It is capable of delivering 500mA output current at 4.0V output with 2V input voltage.
A7531 Key Features
