NCS1002 - ON Semiconductor

NCS1002 Constant Voltage/Constant Current Secondary-Side Controller

The NCS1002 is a highly integrated solution for Switching Mode Power Supply (SMPS) applications requiring a dual control loop to perform Constant Voltage (CV) and Constant Current (CC) regulation. The NCS1002 integrates a 2.5 V voltage reference and two precision op amps. The voltage reference, along with Op Amp 1, is the core of the voltage control-loop. Op.
