Abstract
The utility model relates to a fluorescent lamp ballast driver chip comprising a full-wave rectifier bridge (1) and a power-tube-contained driver chip (2), wherein the full-wave rectifier bridge (1) and the power-tube-contained driver chip (2) are integrated as one chip in an SIP (System in Package) way. The fluorescent lamp ballast driver chip disclosed by the utility model has the advantages of being capable of effectively driving fluorescent lamps and compact fluorescent lamps. The fluorescent lamp ballast driver chip not only has the characteristics of high power factor, low total harmonic distortion and small radio-frequency interference, but also has the advantages of low cost and small PCB (Printed Circuit Board) occupation area, and is applicable to lamp tubes produced by all kinds of manufacturers.
Description
Technical field
The utility model relates to a kind of fluorescent lamp ballast chip for driving.
Background technology
[0002] present, existing fluorescent lamp adopts more discrete device to realize fluorescent lamp ballast, and the shortcoming that such scheme exists has:
1, the discrete device number is many more, and system failure rate can be high more;
2, the cost of system increases;
3, the area with PCB is big.
Summary of the invention
The purpose of the utility model provides a kind of fluorescent lamp ballast chip for driving to the above-mentioned deficiency of present existing fluorescent lamp ballast exactly.
The utility model by full-wave rectification bridge with contain the power tube chip for driving and form, full-wave rectification bridge and contain the form of power tube chip for driving through system in package and be integrated into a chip.
The utility model has the advantages that: this fluorescent lamp ballast chip, effectively driving fluorescent lamp and compact fluorescent lamp.It not only has power factor (PF) height, total harmonic distortion is low, radio frequency interference is little characteristic, is fit to the fluorescent tube of all kinds of manufacturer production, and have cost low, take the little advantage of PCB area.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model by full-wave rectification bridge 1 with contain power tube chip for driving 2 and form, full-wave rectification bridge 1 and contain the form of power tube chip for driving 2 through system in package and be integrated into a chip.
Operation principle: chip by full-wave rectification bridge 1 with contain power tube chip for driving 2 and form; And the form of employing advanced person's system in package (Sip); Development time significantly shortens, and can reduce the printed circuit board sizes and the number of plies through the height integration of encapsulating products, reduces the integral material cost; Effectively reduce the manufacturing and the operating cost of end product, improved production efficiency.In addition, the Sip design has good electromagnetic interference and suppresses effect, can reduce the work of anti-electromagnetic interference aspect to the system combination client.It uses circuit board space still less, lets the end product design have more imaginations space; Have the more compact appearance design personalized, improved value-added content of product with fashion.
Claims (1)
1. fluorescent lamp ballast chip for driving is characterized in that it by full-wave rectification bridge (1) with contain power tube chip for driving (2) and form, full-wave rectification bridge (1) and contain the form of power tube chip for driving (2) through system in package and be integrated into a chip.
