1 / 12 page ![]() CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER AP4306 Data Sheet 1 Sep. 2011 Rev. 1. 4 BCD Semiconductor Manufacturing Limited General Description The AP4306 is a highly integrated solution for a con- stant voltage/constant current mode SMPS application. The AP4306 contains one 1.21V voltage reference, one low voltage reference used in current sensing cir- cuit 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, com- bined with another operational amplifier, makes of an ideal current limiter for output low side current sens- ing. The 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. The AP4306 is available in SOT-23-6 package.
