в–  The LTВ®3585 series are highly integrated ICs designed to
charge photoflash capacitors in digital and film cameras.
A new control technique allows for the use of extremely
small transformers. Each part contains an on-chip high
voltage NPN power switch. Output voltage detection is
completely contained within the part, eliminating the need
for any discrete zener diodes or resistors. The output voltage can be adjusted by simply changing the turns ratio
of the transformer. Adjustable Input Current
