市电供电的led驱动控制器a704（LED driving controller for city power supply A704） This article is contributed by sdtaxyd Pdf documents may experience poor browsing on the WAP side. It is recommended that you first select TXT, or download the source file to the local view. New device applications? LD driving controller for city power supply A74E0 Dafydd A074 is a high canonical version of ADtk, worth 1DemA. If no shutdown drive is required, the maximum voltage V is 2V0. Efficient, off mode, current LD drive controller. The control is used to open constant E, this end is suspended; a S current detection end, 4C The basic structure and work of constant current source circuit The main feature of the system is that it is suitable for international quasi electric power supply. The current sensing resistor is used between the CS and the GND terminal as the principle (525A, also can use the corresponding direct current 8 ~ 6VC1 RS is used to set constant current values; a DD transport C5V The LD driver is a constant current source circuit. By E The constant current source circuit composed of A074 is at D / C CD The drive current depends on the external power input to the power supply. MOSE, driving power, number of FT can be different by not LD; confining element quantity, the area of PS E C Main parameter The basic architecture adds current detection and control to electricity A0s main limit parameter: input voltage path to change the duty cycle of P74WM to achieve current Small, there may be the LD drive circuit is arranged in the maximum value of VD lamp is 3V; adjust the operating temperature range, the output constant current to E frame structure. 2 in its head; the starting current (type value is 5u; low standard low A) One 2 to 8O, the maximum junction temperature is 10. O + 5C:5 DEG C The figure is shown in figure 2. Inside the dashed line in Figure 2 is the bridge Working current (type = 3 code mA) with parameter switching pulse: input voltage VD for 653V; D Fan Wei;.N2 type re
