TPS61062YZFR

Overview

The TPS61062YZFR is a high-frequency synchronous boost converter designed as an LED lighting driver IC. It provides a constant current output of 400 mA with a maximum output voltage of 24 V. The device operates from a single input supply ranging from 2.7 V to 6 V and features a fixed switching frequency of 1 MHz. Packaged in an 8-pin DSBGA, it supports digital brightness control and PWM dimming. The component functions within a temperature range of -40°C to +85°C and includes load disconnect during shutdown for enhanced safety.

Feature Summary

• Synchronous boost topology with constant current regulation for driving white LEDs
• Supports single-wire digital brightness control and PWM dimming interfaces
• Integrates load disconnect functionality during shutdown mode

Applications

• White LED backlighting systems
• Portable electronic device illumination
• General LED lighting driver circuits

Procurement Notes

Verify the specific suffix 'YZFR' against official Texas Instruments documentation to confirm the reel packaging configuration and tape-and-reel specifications. Ensure compatibility with the required DSBGA-8 footprint and soldering profiles. Cross-reference the part number with authorized distributors to validate authenticity and traceability. Confirm that the digital control interface requirements align with the system design before procurement.

Selection Notes

Select this component when a compact solution is needed for driving up to five white LEDs from a low-voltage source. The 1 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 24 V output limit and 400 mA current capability to ensure it matches the LED string requirements. The DSBGA package is suitable for space-constrained designs requiring surface-mount assembly.

Part Context

This part belongs to the TPS6106x family of single-wire digital brightness control LED drivers. It shares architectural similarities with the TPS61060 and TPS61061 but offers specific output voltage and control features tailored for higher voltage LED strings. The family emphasizes safety through load disconnect and efficient power management in portable applications.

Replacement Considerations

The TPS61060DRBR is a related variant within the same family, offering similar functionality with different output voltage characteristics. Verify pinout compatibility and control interface signals when substituting.
