SEA05L - Advanced constant voltage and constant current controller

Description

The device is a 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.

Features

  • Constant voltage and constant current control.
  • Very efficient LED pilot-lamp driver.
  • Wide operating VCC range (3.5 V - 36 V).
  • Low quiescent consumption: 250 µA.
  • Voltage reference: 2.5 V.
  • Voltage control loop accuracy ± 0.5%.
  • Current sense threshold: 50 mV.
  • Current control loop accuracy ± 4%.
  • Low external component count.
  • Open-drain output stage.
  • SOT23-6L package.
