Manufacturer:ST Description:Figure 1 shows one of the most common applications for the white and blue LEDs, which is to configure them in series. In this particular circuit, three white LEDs are used. The advantage of this configuration is that the feedback voltage of the MIC2142, which is a tightly controlled parameter, and R1 set the LED's current. Equal amount of current goes through the series string of white LEDs. Because the LEDs current is proportional to its brightness, the result is uniform bright- ness for all the LEDs. A Zener diode in parallel with the LEDs is recommended to protect the MIC2142 if one of the white LEDs opens for any reason, causing the switch voltage to increase above the maximum rating of the switch pin. The challenge of the series configuration is that the MIC2142 has to boost the output voltage up to the sum of all the forward drop of the white LEDs plus the feedback voltage. |
