Overview
The TPS61158DRVR is a 30V White LED (WLED) driver from Texas Instruments, housed in a 6-WSON package. It operates with an input voltage range of 2.7V to 5.5V and features an integrated 0.6A, 30V internal switch FET and power diode. The device supports up to 8 LEDs in series with 28V open LED protection. It functions as a boost converter running at 750kHz and includes PWM dimming capabilities.
Feature Summary
- Integrates a 0.6A, 30V internal switch FET and power diode for compact design
- Provides 28V open LED protection to safeguard up to 8 series-connected LEDs
- Supports PWM dimming for precise brightness control
Applications
- White LED backlighting systems
- Portable electronic devices requiring WLED drivers
- Boost converter applications for LED strings
Procurement Notes
Verify the specific ordering suffix DRVR against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure compliance with RoHS standards and check for any moisture sensitivity level requirements during storage and handling. Confirm that the component meets the required operating temperature range of -40°C to 85°C for your specific application environment.
Selection Notes
Select this component when a compact solution for driving multiple white LEDs in series is required. It is suitable for applications needing an input voltage between 2.7V and 5.5V. Consider its integrated power stage for space-constrained designs. Evaluate the 750kHz switching frequency for EMI considerations and ensure the load matches the 0.6A current capability.
Part Context
This part belongs to the TPS61158 family of WLED drivers. The DRVR suffix typically denotes a specific packaging configuration, often a reel-based format for surface-mount assembly. It is designed by Texas Instruments for efficient LED illumination in portable electronics.
Replacement Considerations
Check for direct substitutes like the TPS61158DRVT or other variants within the same family that may offer different packaging options. Verify pin compatibility and electrical parameters before substitution.
