AP4313恒流恒压

CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER AP4313 1 Aug. 2006 Rev. 1. 2 BCD Semiconductor Manufacturing Limited Data Sheet General Description The AP4313 is a highly integrated solution for a con- stant 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 refer- ence 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. Features · Constant Voltage and Constant Current Control · Precision Internal Voltage Reference · Few External Components · Easy Compensation · Low Supply Current: 0.5mA · Operating Temperature Range: -40 to 105oC Applications · Adapters · Battery Chargers Figure 1.
