AT1454 Photoflash Capacitor Charger

AT1454 Photoflash Capacitor Charger

The AT1454 series is a charger IC for Photoflash capacitor with soft-start function, an IGBT driver for igniting flash tube, adjustable output voltage and adjustable switch on-time to perform energy transition on each charge cycle. The output voltage can be adjusted by simply changing the turn ratio.

Features

completed to maintain minimum output voltage decay. The device allows user to control automatic refresh rate on Charge pin. While the Ready pin signals that the capacitor is fully charged. AT1454/AT1454A/AT1454B MSOP-10 package. is available in Application
