Description
The EMS1117-3.3 is an electronic component model belonging to the IC Chips product category. It is designed to efficiently charge high voltage photoflash capacitors in both digital and film cameras. Using a flyback topology, this device achieves efficiencies up to four times better than competing flash modules. With a unique adaptive off-time control algorithm, it ensures current-limited continuous mode transformer operation throughout the entire charge cycle, eliminating high inrush current often found in modules.
