Overview
The XC9401C60CSR-G is an AC-DC offline controller for LED lighting, manufactured by Torex Semiconductor. It operates within a wide input voltage range of 85 VAC to 270 VAC and supports a maximum supply voltage of 270 V. The device utilizes a buck topology to deliver a regulated output current of 120 mA through a single channel. Designed for surface-mount applications, it is housed in a compact SOT-25 package. The component functions effectively across an extended temperature range from -40°C to +85°C and incorporates PWM dimming capabilities for precise light control.
Feature Summary
- Integrates PWM dimming functionality for accurate brightness adjustment
- Supports high-voltage AC input ranges suitable for direct mains connection
- Utilizes a synchronous buck topology for efficient power conversion
Applications
- LED lighting driver circuits
- Offline AC-DC power supplies
- General illumination systems
Procurement Notes
Verify the specific datasheet revision and ordering suffixes to ensure compatibility with required thermal and electrical specifications. Confirm that the SOT-25 package dimensions align with the target PCB layout constraints. Ensure compliance with RoHS directives as indicated in the manufacturer's documentation before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a single-channel LED driver with integrated PWM dimming. The wide input voltage range makes it suitable for universal AC mains operation without additional pre-regulation stages. Consider the 120 mA output limit when determining the number of series-connected LEDs or load requirements for the specific design.
Part Context
This part belongs to the XC9401 series of LED lighting drivers designed for cost-effective and compact solutions. The series focuses on providing reliable performance for general lighting applications using standard off-the-shelf components. The XC9401C60CSR-G specifically addresses the need for efficient power management in small form-factor LED fixtures.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the same pinout configuration, output current rating, and package type to avoid redesign efforts.
