Overview
The BCR430UXTSA2 is a linear low-voltage-drop LED driver IC manufactured by Infineon Technologies. It operates within a supply voltage range of 6 V to 42 V and supports an output current up to 100 mA, with a typical setting of 20 mA. The device features a maximum power dissipation of 600 mW and achieves a voltage drop as low as 0.135 V. Packaged in a PG-SOT23-6 surface-mount case, it is designed for industrial applications requiring compact PCB layouts and high design flexibility.
Feature Summary
- Ultra-low voltage drop capability suitable for scenarios where supply voltage closely matches LED forward voltage
- Supports PWM dimming via the RS pin for flicker-free light output
- Enables compact printed circuit board designs due to minimal external component requirements
Applications
- LED strips and signage
- Retail lighting
- Emergency lighting
- Architectural LED lighting
Procurement Notes
Verify the specific ordering suffix XTSA2 to confirm the tape-and-reel packaging format. Ensure compatibility with the target industrial temperature range and validate that the 600 mW thermal dissipation limit meets the application's heat management requirements before finalizing procurement.
Selection Notes
Select this component when designing systems with limited space and a need for precise current regulation without complex switching topologies. It is appropriate for DC-powered LED strings where the input voltage remains within the specified 6 V to 42 V window and low dropout performance is critical for efficiency.
Part Context
This part belongs to the BCR family of linear LED drivers from Infineon Technologies. It shares functional similarities with the BCR431U but differs in specific voltage drop characteristics. The family targets commercial and automotive interior lighting, offering a balance between cost-effectiveness and performance for low-power LED applications.
Replacement Considerations
The BCR431U is a documented comparable product within the same Infineon portfolio. Verify if the specific voltage drop differences align with the system's headroom requirements before substituting.
