BATTERY BACKUP SWITCHING IC

Rev.3.0_01

S-8424A Series

Reference data: Dependency of output current (IOUT), load capacitance (COUT), input variation width (

ΔVIN),

temperature (Ta)

For reference, the following pages describe the results of measuring the ringing amounts at the VOUT and

VRO pins using the output current (IOUT), load capacitance (COUT), input variation width (

ΔVIN), and

temperature (Ta) as parameters.
