LNK6764V is a offline switcher integrated circuit (IC) developed by Power Integrations, delivering an Universal Continuous Output Voltage (UCOV) compliant precision AC-DC power supply. Its power supply range includes AC and DC energy sources from 85V- to 305V- and from 180V~280V~, respectively.The device provides a controllable output of up to 4V and a maximum output current of 1.4A at peak load. Its power reach is between 1.3W and 8.3W and its working temperature range is from -40°C to 70°C. The device features a constant frequency flyback control topology that makes it suitable for a wide range of applications such as consumer electronics and industrial systems.LNK6764V is designed on a low power platform, meaning that it uses fewer components than traditional solutions, making it ideal for space-restricted designs. Its integrated 800V MOSFET allows for an extended range of operating voltages, resulting in a high AC-input mains receptacles protection, while its hybrid control methodology delivers an optimal balance of efficiency, safety-interlock protection and flexibility. It complies with the highest industry standards and it is suitable to the ETL60950-1, IEC60950-1, UL60950-1, EN60950-1, EN 55022 and EN61000-6-2.The device’s advanced EMI source control reduces cross-talk and radiated emissions, making it suitable for use in applications with strict EMI limits. It incorporates an internally protected digital-controlled start-up control structure with accurate output voltages, improved line regulation and fast transient response time.The working principle of the LNK6764V is based on a current-mode control technique. An error amplifier (EA) senses an error voltage between its output and a reference voltage, then produces an output signal called the error signal. This signal is then amplified by a main amplifier, resulting in the output current of a power-stage MOSFET. The number of switches is adjusted by the error signal and the voltage in the draining capacitor; hence, controlling the output voltage.Because of its extended power range, controllable output, high efficiency and its industry standard compliance, the LNK6764V is a compact ideal device for applications such as consumer electronics and industrial systems. Its combination of features, such as accurate output voltage, improved line regulation and fast transient response time, make it well-suited to a variety of power supply applications.`
