... LT3585-0/LT3585-1 LT3585-2/LT3585-3 U OPERATIO The LT3585 series of parts operate on the edge of dis- continuous conduction mode. When CHRG/IADJ is driven higher than 1.1V, the master latch is set. This enables the part to deliver power to the photofl ash capacitor. When the power switch, Q1, is turned on, current builds up in the primary of the transformer ...

... LT3585-2 have a current limit in between that of the LT3585-1 and the LT3585-3. Transformer Design The fl yback transformer is a key element for any LT3585-0/ LT3585-1/LT3585-2/LT3585-3 design. It must be designed carefully and checked that it does not cause excessive cur- rent or voltage on any pin of the part. The main parameters that need to be designed are shown in Table 1. The fi ...

... 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. Table 2 shows the details of several of these transformers. Table 2. Predesigned Transformers—Typical Specifi cations Unless Otherwise Noted ...

The ENABLE pin is used to enable or disable the auto-refresh charging mode. Without an auto-refresh circuit, the output voltage will droop due to output capacitor and output diode leakage currents ...
