U U APPLICATIO S I FOR ATIO Choosing the Right Device (LT3585-0/LT3585-1/LT3585-2/LT3585-3) The only difference between the four versions of the LT3585 series is the peak current level. For the fastest possible charge time, use the LT3585-3. The LT3585-1 has ...

... Although this would result in a very low leakage spike on the SW pin, the parasitic capacitance of the transformer would become large. This will adversely affect the charge time of the photofl ash circuit. Linear Technology has worked with several leading magnetic component man- ufacturers to produce predesigned fl yback transformers for use with the LT3585-0 /LT3585-1/LT3585-2/LT3585-3 ...
