General 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 SOT-23-6 package.
