Overview
The TPS61161ADRVR is a white LED driver IC featuring digital and PWM brightness control. It utilizes a boost topology with an internal switch, supporting up to 38 V output voltage and 700 mA output current. The device operates within a 2.7 V to 18 V supply range at a fixed 600 kHz switching frequency. Packaged in a compact 6-WSON (2x2 mm) format, it includes open LED protection and functions across a -40°C to +85°C temperature range.
Feature Summary
- Integrates digital and PWM dimming capabilities for precise brightness regulation
- Includes built-in open LED protection circuitry
- Features a compact 2mm x 2mm WSON package design
Applications
- White LED backlighting systems
- Portable electronic displays
- General LED lighting applications
Procurement Notes
Verify the specific suffix 'RVR' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the standard commercial operating temperature range of -40°C to +85°C meets your environmental specifications. Ensure the 6-WSON footprint matches your PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a single-channel boost driver with integrated PWM dimming is required for space-constrained designs. It is suitable for driving series-connected white LEDs where input voltages vary between 2.7 V and 18 V. Consider alternative automotive-qualified variants if operation beyond 85°C or AEC-Q100 certification is necessary.
Part Context
This part belongs to the TPS61161A family of LED drivers from Texas Instruments. It shares core electrical characteristics with the TPS61160 but offers extended output voltage capabilities up to 38 V. The device is designed as a cost-effective solution for portable devices requiring efficient white LED illumination with simple control interfaces.
Replacement Considerations
The TPS61161ADRVT serves as a direct pin-compatible alternative with identical electrical performance but differs in reel packaging quantity. Verify that any substitute maintains the same 6-WSON footprint and thermal dissipation requirements.
