LT3485-0/LT3485-1/LT3485-2/LT3485-3 are photoflash capacitor chargers with output voltage monitor and integrated IGBT drive.
The LT3485 family are highly integrated photoflash charger ICs with an on‑chip IGBT driver, voltage‑output monitor and support for small transformers. They operate from 1.8 V to 16 V and can be powered by two AA cells, a single Li‑ion cell, or any suitable supply.
