Description
- Typical Application Circuit for High Charge Rate LT3420 Photoflash Circuit. 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
