SEA05TR

Power Management - Specialized Overview

The SEA05TR is a highly integrated LED lighting driver IC from STMicroelectronics, designed for space-constrained applications like adapters and chargers. It operates as a secondary side switch-mode power supply controller with dual control loops for constant voltage (CV) and constant current (CC) regulation. The device features an open-drain output stage, a 2.5 V voltage reference, and low-side current sensing with a 50 mV threshold. It supports Boost and Buck topologies within a 3.5 V to 36 V input range. Quiescent consumption is 200 µA, and it functions in temperatures from -40°C to +150°C.

Power Management - Specialized Feature Summary

• Dual control loop architecture enabling simultaneous constant voltage and constant current regulation for precise power delivery.
• Integrated low-side current sensing circuit with a 50 mV threshold for accurate current monitoring.
• Highly compact SOT-23-6 package design optimized for space-critical electronic applications.

Power Management - Specialized Applications

• LED pilot-lamp drivers
• AC/DC switching power supplies
• Compact adapters and chargers

Power Management - Specialized Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official documentation. Ensure the selected variant matches the required operating temperature range and package type for your design constraints.

Power Management - Specialized Selection Notes

Select this component for designs requiring minimal external components due to its high integration level. Consider the 200 µA quiescent current for efficiency requirements. Verify that the SOT-23-6 package fits the PCB layout constraints and thermal management needs of the target application.

Power Management - Specialized Part Context

This part belongs to the SEA05 series of LED drivers. It shares core functionalities with variants like SEA05LTR but differs in packaging configuration. The series is positioned for efficient SMPS control in consumer electronics where board space is limited.

Power Management - Specialized Replacement Considerations

Check for SEA05LTR as a potential alternative if reel packaging is acceptable. Verify pin compatibility and electrical specifications before substitution. Consult official datasheets for any functional differences between suffixes.
