CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER
Description
The AP4313 is a highly integrated solution for a constant
voltage/constant current mode SMPS application.
The AP4313 contains one 1.21V voltage reference with 1%
accuracy, one current sensing circuit and two operational amplifiers.
Combining the voltage reference with one operational amplifier makes
AP4313 an ideal voltage controller for use in adapters and battery
chargers. The other low voltage reference combined with the other
operational amplifier makes it an ideal current limiter for output low
side current sensing.
The AP4313 is available in SOT26 package.
