Active-Semi ACT355A
The ACT355A ensures safe operation with complete protection against all fault conditions. The ACT355A ActivePSR is optimized for costsensitive applications, and utilizes Active-semi’s proprietary primary-side feedback architecture to provide accurate constant voltage, constant current (CV/CC) regulation without the need of an optocoupler or reference device. The ACT355A is optimized for 2.5W to 3.5W applications (such as 5V/500mA to 5V/700mA CV/CC chargers).| Part No. | ACT355A |
