LTC3470AIDD-2TRPBF - Brand New Linear Technology IC Chips
-
Description
The LTC3470AIDD-2TRPBF is an IC chip that is designed to charge high voltage photoflash capacitors quickly and efficiently. It is suitable for use in both digital and film cameras, offering efficiencies up to four times better than competing flash modules. The device utilizes a flyback topology and a unique adaptive off-time control algorithm to maintain current-limited continuous mode transformer operation throughout the charge cycle, eliminating high inrush current often found in modules.
