Standard 8 pin DIL IC marked thus: Code: A LC56 ___ 383 It's on a small PCB along with a diode, a red LED, 2 electrolytic caps and an inductor. The PCB is marked ZB195-1 161030 the PCB is attached by 2 flying leads marked V+ and V- to the terminals of a standard car cigarette lighter plug. the PCB also has two flying leads one red one black, which exit the board into a black 2 core cable that terminates in a micro usb plug. the housing of the unit is moulded as a plug for a car cigarette lighter, and a sticker on the outside indicates input voltage 12-24v DC & output voltage 5V DC current 1A. Does anyone happen to know where to find a datasheet for the chip marked LC56, or know of an alternative moniker for it?
