Product Summary
The LT3484EDCB-1#PBF is a Photoflash Capacitor Charger. The LT3484EDCB-1#PBF family of photoflash capacitor charger ICs is designed for use in digital camera and mobile phone applications where space is at a premium. The LT3484EDCB-1#PBF’s patented control technique allows it to use extremely small transformers, and the improved NPN power switch requires no external Schottky diode clamp, reducing solution size. Output voltage detection requires no external circuitry as the transformer turns ratio determines final charge voltage. The devices feature a VBAT pin, which allows the use of 2 alkaline cells to charge the capacitor. The applications of the LT3484EDCB-1#PBF include Digital Camera and Cell Phone Flash Charger.
