LC5545LD

Overview

The LC5545LD is an AC-DC offline switcher IC from Sanken Electric, designed as an LED driver. It operates in a through-hole 8-DIP package and supports an operating temperature range of -55°C to 125°C. The device features a maximum on-resistance (RDS(on)) of 3.95 Ω. It is capable of delivering a maximum output power ranging from 20 W to 80 W depending on the specific application configuration.

Feature Summary

Integrated single-stage off-line switcher architecture for LED driving applications
Through-hole mounting style providing structural integrity
Wide operating temperature range ensuring thermal stability

Applications

LED lighting systems
AC-DC power conversion
Offline switcher circuits

Procurement Notes

Verify the exact part number suffix and manufacturer documentation before procurement. Confirm that the 8-DIP through-hole package matches your PCB layout requirements. Ensure the component's thermal characteristics align with your system's operating environment limits. Cross-reference specifications with official Sanken Electric datasheets to validate performance parameters.

Selection Notes

Select this component when designing LED drivers requiring an integrated offline switcher solution. Consider the 3.95 Ω RDS(on) value for efficiency calculations within the 20 W to 80 W power range. The through-hole package is suitable for applications prioritizing mechanical robustness. Verify compatibility with your target AC input voltage and LED load requirements against official technical data.

Part Context

This component belongs to Sanken Electric's LC5545 series of power management ICs. It is categorized under LED drivers and AC-DC offline switchers. The series includes variants such as LC5546 and LC5547, which share similar architectural functions but differ in internal resistance and power handling capabilities.

Replacement Considerations

LC5546LD and LC5546LF are related series components with different RDS(on) values. LC5547LF offers lower resistance at 1.1 Ω. Verify electrical compatibility and pinout alignment before substituting these parts.
