          Nanjing Weimeng launches control chip IC designed for LED driver

          Nanjing Micro One Electronics Inc. has introduced a high-performance green power management chip IC-ME8108 with pulse frequency modulation (PFM) technology, which is specially designed for cost-effective battery chargers, power adapters and Low power AC/DC switching power supply controller designed for LED drive.

          The ME8108 contains 5V built-in voltage, voltage feedback and digital circuits, constant peak current setting circuit, leading edge blanking circuit, optimized triode drive circuit, overvoltage protection circuit, open circuit protection circuit, PFM control and constant voltage constant current. Adjust the circuit. With low power consumption, low startup current and low EMI, the maximum efficiency can reach more than 80%, and the starting voltage, output voltage and maximum power can be adjusted. The product uses pulse frequency modulation (PFM) technology to operate the flyback circuit in discontinuous current mode (DCM), using advanced primary feedback control (PSR) technology to achieve constant voltage / constant current (CV / CC) accuracy Control, without the need of optocoupler, secondary feedback circuit and loop compensation circuit to achieve stable and reliable operation of the system.

          ME8108 can be widely used in various low-power AC/DC switching power supply solutions, such as: mobile phone chargers, power adapters, etc. In addition, because the chip integrates constant current function, it can also be widely used in low-power LED driving solutions. in. Use this chip to build an AC/DC converter solution that uses few external components and maintains high performance over a wide AC voltage input range.
