LED driver scheme without power supply -DR3062

Taiwan advanced power design company has recently launched the technology of amorphous silicon capacitors, no inductance, no need to convert the transformer without power LED driver. The utility model solves the problem that the power supply is limited by the life of the electrolytic capacitor, the volume of the transformer and the driving efficiency are low.

The traditional LED lighting design, basically divided into two parts, that is, LED lamp and the power supply part of the power module. In the LED lamp grain part, because of the rapid expansion of production scale, resulting in a rapid decline in costs, the cost per unit of lighting gradually with the traditional lighting enough to contend with. Only the power module part, limited to the traditional AC to DC hardware architecture, there is no significant change in costs.

In order to solve the plight of the cost of the power supply part of the technology, the introduction of direct use of AC lighting LED Driver IC --- DR3062. Because they don't have to bother to DC, so you do not have to use the volume of the transformer is relatively large, can save considerable space. Of course, you will no longer have to not resistant to electrolytic capacitor used for a long time, greatly improve the reliability of products, LED lighting has become really can reach the LED lamp bulbs allowed by the longest service life of the product, from the short life cycle of the electrolytic capacitor, which is LED lighting on the earth should promise:: green, green, long term.

DR3062 basically a total input power of about 7W, can drive the general (Vf about 3.0V) of the 72 particles of the lamp, the resulting brightness is greater than about 550 lumens. Divided into TSSOP14 and SOP8 two kinds of packaging. According to the different photoelectric characteristics of the lamp, the customer can also be configured with different number of lamp grain combinations, while also providing relevant software tools to facilitate the customer to make the necessary changes.

All functions have been integrated into a single chip, the number of external components will be significantly reduced. The design of the device becomes very easy for people interested in the promotion of LED lighting manufacturers, almost as long as can get housing, you can begin production of its own brand of lamps. This concept, in fact, the concept of a single chip with MediaTek exactly the same, that is: customers need to pay attention to the assembly and marketing channels, all the technical problems to help customers solve the problem.

Customers may have doubts: so low cost products in the security protection on the fly it?

DR3062 has also been considering these issues for the customer, the chip in the static, over-voltage, lightning, surge and other special application environment, have been designed corresponding protection measures.

The real experience of the use of the product, it is necessary to go through considerable time. In fact, based on the conservative principle, DR3062 has been used by a handful of long term partners in the field test for nearly a year. The overall results are satisfactory. After getting quite positive feedback from these customers, the company began to make a comprehensive promotion of all LED lighting customers. Shenzhen City Rui Technology Co., Ltd. signed an agent for Huajing, formally accepted the customer sample.
