TPS61050AYZGT

Overview

The TPS61050AYZGT is a high-power white LED driver IC from Texas Instruments, designed for camera flash applications. It features a 1.2A output current capability and operates within an input voltage range of 2.5V to 6V. The device utilizes a 2MHz switching frequency to achieve efficient step-up conversion. It is housed in a compact 12DSBGA package, suitable for surface mount installation. The component supports PWM dimming for brightness control and includes load disconnect functionality during shutdown.

Feature Summary

• Supports PWM dimming for precise brightness regulation
• Integrates internal switch for compact design
• Provides load disconnect during shutdown mode

Applications

• Camera flash lighting systems
• Mobile device illumination
• Compact LED driver circuits

Procurement Notes

Verify the specific suffix 'A' against official Texas Instruments documentation to confirm pinout and electrical characteristics match the required design specifications. Ensure the 12DSBGA footprint aligns with PCB layout constraints. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement decisions.

Selection Notes

Select this component when a high-current boost converter is needed for single-white-LED applications. The 2MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 12DSBGA package size for space-constrained mobile designs requiring integrated power switching capabilities.
