AP4320中文资料Constant Voltage and Constant Current Controller数据手册Diodes规格书

描述 Description

The AP4320 is a highly integrated solution for a constant voltage/constant current mode SMPS application.

\t 

\tThe AP4320 contains one 2.5V voltage reference and two operational amplifiers. The 2.5V voltage reference, combined with one operational amplifier, makes of an ideal voltage controller for use in adapters and battery chargers. The low voltage reference, combined with another operational amplifier, makes of an ideal current limiter for output low side current sensing.

\t 

\tThe AP4320 is available in SOT26 package.
