General Description
The AAT6900, a photoflash capacitor charger using the fly back topology, is designed for use in digital cameras and mobile phones. Not only does it have an output floating protection to avoid uncontrollable output voltage, but it is also equipped with modifiable charging current capacity, which makes AAT6900 suitable for a variety of applications. It allows charging of the capacitor using one lithium-ion battery or two to three AA batteries. The AAT6900 integrates an IGBT driver and a built-in 45V MOSFET. The READY pin operates as an on indicator to indicate charge completion. The AAT6900 is available in a 10-lead VSON package.
