This is preliminary information on a new product now in development or undergoing evaluation. It is an advanced constant voltage and constant current controller with a very efficient LED pilot-lamp driver. It has a wide operating voltage range, low quiescent consumption, and accurate voltage and current control loops. It is suitable for applications such as AC-DC adapters, battery chargers, and SMPS with LED pilot-lamps.
The SEA05L is a highly integrated solution designed for SMPS applications, featuring constant voltage (CV) and constant current (CC) regulation. It includes an internal voltage reference, two operational amplifiers with OR-ed open-drain outputs, a low-side current sensing circuit, and a dedicated LED pilot-lamp driver.
