LINEAR TECHNOLOGY  LT3468ES5#TRMPBF  芯片, 闪光灯电容充电器, TSOT23-5

The is a highly integrated Photoflash Capacitor Charger IC designed to charge photoflash capacitors in digital and film cameras. A patented control technique allows for the use of extremely small transformers. Each device contains an on-chip high voltage NPN power switch. Output voltage detection is completely contained within the device, eliminating the need for any discrete Zener diodes or resistors. The output voltage can be adjusted by simply changing the turn ratio of the transformer. The LT3468 has a primary current limit of 1.4A. Aside from the differing current limit, the device is otherwise equivalent. The CHARGE pin gives full control of the part to the user. Driving CHARGE low puts the part in shutdown. The DONE pin indicates when the part has completed charging.
