NCP11184A65P25WGEVB 25W Auxiliary Power Supply for White Goods and Industrial Equipment with NCP11184A65
●NCP1118x is a highly enhanced switcher integrating a peak current mode PWM controller employing mWSaver and frequency reduction technology and a highly robust 800 V Super−junction II MOSFET. Additionally, it features a high−voltage startup circuit, frequency reduction, slope compensation, constant output power limit, and highly reliable and various protections. As a results, it allows designing cost−effective off−line power supplies using NCP1118x with less BOM counts and smaller PCB size and high efficiency as well. Additionally, it could get lowst and by power consumption less than typically 40 mW despite of multiple outputs.
●On top of that, NCP1118x features variety of protections for highly reliable power supply design such as a feedback pin open−loop protection (OLP), current−sense resistor short protection (CSSP), brown−out, line over−voltage protection (Line−OVP) using an line voltage sensing pin operated with auto−recovery operation and constant over−power protection. This design note demonstrates those protections under various conditions.
●Key Features:
■Peak Current Mode Controller Integrated 800 V SJ−IIMOSFET, High Voltage Start−up, Soft−Start, and Slope Compensation
■mWSaver Technology Provides Industry's Best−in−Class Standby Power
