It's a little wisp of a circuit that allows you to drive a blue or white LED from a low voltage. Normally, if you want to light up a blue or white LED you need to provide it with 3 3. 5
return to HOME (More projects including LED projects) White LED Drive Circuit Connecting it in the same circuit (2N4401, 330 Ohms, white LED) with a 1. 5 volt power supply, I saw that the LED lit up, but not as bright as with the bobbin core, but then again, I had only put 20 turns on the toroid. white led driver from 1 5v5
Jun 25, 2009 Are u looking for a white led driver its here post your comments R5 can be used for current control, R9 and C3 for frequency controll enjoy: idea: : idea: 1. 5 v led driver Most solar garden lights have a simple voltage stepup circuit similar to yours. 1 members found this post helpful. ZXSC380 Single or multi cell LED driver solution multi cell LED driver for applications where stepup voltage conversion from a very low input voltage is required. These applications mainly operate from 1. 5V or 1. 2V cells. The IC LED backlights White LED driver Pin connections Typical application circuit VCC GND VOUT Top view 1 LED currents of up to 40mA can be supported over a wide range of input supply voltages from 2V to 7V, making the device ideal for batterypowered applications. A high voltage output stage allows up to 4 White LEDs to be driven in series.
