BCD Semiconductor Manufacturing Limited AP4313
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. The other low voltage reference combined with the other operational amplifier makes it an ideal current limiter for output low side current sensing.| Part No. | AP4313 |
