TPS61162YFFR

Overview

The TPS61162YFFR is a dual-channel white LED driver IC manufactured by Texas Instruments, designed for backlight applications. It features a step-up (boost) DC-DC regulator topology with two independent outputs. The device supports both analog and PWM dimming methods to control LED brightness. It operates within an input voltage range of 2.5 V to 5.5 V and delivers up to 30 mA per channel. The integrated boost converter switches at a frequency of 1.2 MHz. The component is housed in a compact 9-pin DSBGA package and is rated for operation between -40°C and +85°C.

Feature Summary

Dual-channel architecture providing independent current regulation for two white LEDs
Integrated boost converter enabling operation from low input voltages
Supports both analog and pulse-width modulation (PWM) dimming techniques

Applications

Smartphone LCD backlight systems
Tablet display illumination
Portable electronic device lighting

Procurement Notes

Verify the specific suffix 'YFFR' against the official Texas Instruments datasheet to confirm package type and tape/reel specifications. Ensure the design accounts for the NRND status if applicable to similar variants, as availability may vary. Confirm thermal performance requirements for the DSBGA-9 package under maximum load conditions before finalizing procurement.

Selection Notes

Select this component when a dual-channel solution is required for WLED backlights in space-constrained portable devices. The 1.2 MHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider the 30 mA output limit per channel to ensure it meets the target LED string current requirements without exceeding device capabilities.

Part Context

This part belongs to the TPS61162 family of LED drivers from Texas Instruments. It is specifically engineered for mobile phone and tablet backlighting applications requiring high efficiency and small footprint. The family typically includes variants with different packaging or pin configurations, but all share the core dual-channel boost driver functionality.

Replacement Considerations

Check for direct substitutes such as the TPS61162AYFFR or TPS61162DYFFR, which may offer minor variations in packaging or ordering suffixes. Verify compatibility with existing PCB footprints and control signals before substituting.
