产品概述
SEA05LTR is an advanced constant voltage and constant current controller with efficient LED pilot-lamp driver. It is highly integrated solution for SMPS applications, with an LED pilot-lamp requiring a dual control loop to perform CV (constant voltage) and CC (constant current) regulation. The IC allows very efficient LED pilot-lamp driving which helps to reduce the standby consumption of the SMPS. This driver integrates a voltage reference of two op-amps and a low side current sensing circuit with an LED pilot-lamp driver. Pin is implemented with an open-drain mosfet driven by square waveform with 12.5% duty cycle at 1KHz that allows reducing LED consumption. This driver is widely used in applications such as AC-DC adapter with LED pilot-lamp, battery chargers with LED pilot-lamp, SMPS with LED pilot-lamp etc.
