TPS61050YZGT

Overview

The TPS61050YZGT is a high-power white LED driver IC manufactured by Texas Instruments. It features a synchronous boost topology with a constant current sink, designed to drive single white LEDs. The device operates within an input voltage range of 2.5 V to 6 V and delivers an output current of 1.2 A. It utilizes a DSBGA-12 package and supports PWM dimming. The component functions as a DC/DC step-up regulator suitable for camera flash applications.

Feature Summary

• Integrates a synchronous boost converter with a constant current sink for precise LED driving
• Supports I2C compatible interface for digital control
• Includes load disconnect functionality during shutdown mode

Applications

• Camera flash systems
• High power white LED lighting
• Portable electronic devices requiring compact LED drivers

Procurement Notes

Verify the specific suffix (YZGT vs YZGR) against your bill of materials, as packaging formats differ. Confirm that the DSBGA-12 package footprint matches your PCB layout. Ensure the design accommodates the specified thermal dissipation requirements for the target application environment.

Selection Notes

Select this component when a compact solution for driving single high-power white LEDs is required. It is appropriate for designs needing a 1.2 A constant current source from a low-voltage supply. Consider the DSBGA-12 package constraints and the need for I2C or PWM control interfaces in the system architecture.

Part Context

This part belongs to the TPS61050 series of LED drivers. It is functionally similar to the TPS61050YZGR, differing primarily in reel packaging rather than electrical characteristics. The device is categorized under LED Lighting Drivers and DC/DC Regulators within Texas Instruments' portfolio.

Replacement Considerations

The TPS61050YZGR is a direct alternative with identical electrical specifications but differs in tape and reel packaging configuration.
