AP4306中文资料Constant Voltage and Constant Current Controller数据手册Diodes规格书

描述 Description

The AP4306 is a highly integrated solution for a constant voltage/constant current mode SMPS application.

\t 

\tThe AP4306 contains one 1.21V voltage reference, one low voltage reference used in current sensing circuit and two operational amplifiers. The 1.21V 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 AP4306 is fully compatible with AP4305 in functionality and electrical characteristics except its lower reference voltage for current control loop, thus higher power efficiency in SMPS applications such as low power charger can be realized with AP4306 compared to AP4305.

\t 

\tThe AP4306 is available in SOT26 package.
