TPS61163AYFFR

Overview

The TPS61163AYFFR is a dual-channel white LED driver IC from Texas Instruments, housed in a 9-DSBGA package. It operates as a boost DC-DC regulator with an input voltage range of 2.7V to 6.5V and output voltages up to 38V. The device supports analog and PWM dimming with a switching frequency of 1.2MHz. Each channel provides up to 30mA output current. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture for independent white LED control
• Integrated boost converter topology for efficient power regulation
• Supports both analog and pulse-width modulation dimming methods

Applications

• Smartphone backlight systems
• Mobile device illumination circuits
• Portable electronic display lighting

Procurement Notes

Verify component authenticity through authorized channels. Confirm the 9-DSBGA package integrity and check for RoHS compliance documentation. Ensure the specific AY suffix matches design requirements. Review datasheet revisions for any functional updates before integration into final products.

Selection Notes

Select this component for space-constrained mobile designs requiring dual-channel LED drive. Consider the 1.2MHz frequency for inductor size optimization. Verify that the 30mA per channel limit meets load requirements. Evaluate thermal performance within the specified operating temperature range during system design.

Part Context

This part belongs to the TPS61162/63 family of LED lighting drivers. It shares architectural similarities with the TPS61162 but offers specific electrical characteristics tailored for modern smartphone applications. The DSBGA package enables compact PCB layouts compared to larger surface-mount alternatives.

Replacement Considerations

The TPS61163AYFFR is marked as Not Recommended for New Designs (NRND). The TPS61163YFFR is listed as a direct substitute. Verify pin compatibility and electrical specifications before substitution.
