SEA05L
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.
Key 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 ponent count
- Open-drain output stage
Applications
- AC-DC adapter with LED pilot-lamp
