AC DC rechargeable Led bulb driver mainly build with two different ICS. First one is drive several leds in series when power is available. Second one is drive several leds in parallel, also charge the lithium battery, when power cut happens the second IC drive the leds in parallel using the battery. QW2886, XT1011BS are some name of the second ICs, but these ICs are not easily available in the market, can anyone tell me the alternative of this ICs which is easily available in Digikey, or Mouser etc.?
Please see the attached file for QW2886 datasheet.
