The power product designed and produced by FMD has s series of highly integrated power management control chip, the main function of which is to convert the AC (90Vac~264Vac) to DC. The products of this series implement differentiation development and have comprehensive product function and wide covering range, which include various application fields such as primary-side feedback CV/CC control chip, secondary-side feedback CV control chip, synchronous rectifier, small home appliance CV power supply chip, isolated LED constant current chip, non-isolated LED constant current chip, high PF LED constant current chip and so on.
Besides, by adopting FMD patent control technique, the products of this series are with high CV/CC precision, high efficiency, low power consumption, small volume and low cost, which can meet customer demand in various power control applications to largest extent. Furthermore, the products can provide relatively large amount of protective functions, including over-voltage protection, under voltage protection, short circuit protection, open circuit protection and over-temperature protection, etc, which can protect the system from damage at first time when the power fault occurs, and will restart the system after the faults disappear, guaranteeing the safety, reliability and service life of the system.
The products of this series are mainly used in battery charger of various digital products, power adapter of various household appliances, LED driving power and other fields, and its power consumption range is 0~60W.
