TPS61050AYZGR

Overview

The TPS61050AYZGR is a high-power white LED driver IC from Texas Instruments, featuring a 2-MHz synchronous boost converter topology. It delivers a regulated output current of 1.2 A, specifically optimized for camera flash applications. The device operates within an input voltage range of 2.5 V to 6 V and supports PWM dimming for brightness control. Packaged in a compact 12-DSBGA format, it integrates internal switches and includes features such as load disconnect during shutdown. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 2-MHz synchronous boost converter for efficient power conversion.
• Provides precise PWM dimming capability for controlled LED brightness.
• Includes internal switches to minimize external component count.
• Features load disconnect functionality during shutdown mode.

Applications

• Camera flash lighting systems
• High-power white LED drivers
• Mobile device illumination circuits

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official documentation to confirm pinout compatibility and functional specifications. Ensure the 12-DSBGA package dimensions align with the target PCB footprint. Cross-reference the thermal performance data with the intended application environment to guarantee operation within the specified -40°C to +85°C temperature range.

Selection Notes

Select this component for applications requiring high peak current output for short-duration pulses, such as photographic flashes. The integrated synchronous design reduces external inductor requirements compared to asynchronous alternatives. Consider the 2-MHz switching frequency when designing layout constraints to manage electromagnetic interference. Verify that the input voltage source remains stable within the 2.5 V to 6 V operational window.

Part Context

This part belongs to the TPS61050 series of high-power LED drivers designed by Texas Instruments. The series focuses on providing robust current regulation for white LEDs in portable electronics. The YZGR suffix indicates the specific tape-and-reel packaging configuration used for automated assembly processes, distinguishing it from cut-tape or tray variants.
