Typical Application Circuit for Professional Charger uses Multiple LT3420 Circuits in Parallel to Charge Large Photoflash Capacitors Quickly. The LT3420 charge high voltage photoflash capacitors quickly and efficiently. Designed for use in both Digital and film cameras, these devices use a flyback topology to achieve efficiencies up to four times better than competing flash modules. A unique adaptive off-time control algorithm maintains current-limited continuous mode transformer operation throughout the entire charge cycle, eliminating the high inrush current often found in modules
