说明
- Typical Application Circuit for Small Size LT3420-1 Photoflash Circuit. The LT3420-1 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
