Overview
The TPS922050D2DRLR is a synchronous buck LED driver IC from Texas Instruments, designed for high-efficiency lighting applications. It supports an input voltage range of 4.5 V to 60 V and delivers up to 1 A output current. The device operates at a fixed switching frequency of 400 kHz and features analog or PWM dimming capabilities. Packaged in an 8-pin SOT-583 (DSGR) reel, it functions within a temperature range of -40°C to +125°C. This component integrates protection features suitable for automotive and industrial LED systems.
Feature Summary
- Synchronous buck topology ensures high efficiency across the operating range
- Supports both analog and pulse-width modulation dimming methods
- Integrated protection mechanisms safeguard against overcurrent and thermal events
Applications
- Automotive exterior lighting modules
- Industrial LED illumination systems
- General solid-state lighting fixtures
Procurement Notes
Verify the specific ordering suffix D2DRLR matches the required package type and tape/reel specifications. Confirm that the 60V maximum input rating aligns with your system's supply voltage. Ensure the SOT-583 footprint corresponds to your PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact synchronous buck solution is required for single-channel LED driving. It is appropriate for designs needing precise current regulation with integrated dimming control. Consider the thermal performance in the small package when determining heatsinking needs for continuous operation.
Part Context
This part belongs to the TPS922050 family of LED drivers. It complements other variants like the TPS922050D1DRLR by offering specific package and configuration options. The series targets applications requiring robust performance in space-constrained environments.
Replacement Considerations
Direct substitutes include the TPS922050D1DRLR, which shares similar electrical characteristics but may differ in package or internal configuration details. Verify pin compatibility and thermal dissipation requirements when swapping between these variants.
