TPS61160DRVRG4 Equivalent & Substitute Parts

Part Overview

The TPS61160DRVRG4 is a LED Driver IC from Texas Instruments designed for step-up (boost) DC-DC regulation with PWM dimming capability. This single-output regulator operates from a 2.7V to 18V supply and delivers up to 700mA switch current at 26V output, making it suitable for backlight applications. The device is discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for seamless design substitution.

Substitute Part Grouping Explanation

Substitution of the TPS61160DRVRG4 is determined by strict equivalence across all electrical and mechanical parameters. The substitute parts TPS61160ADRVR, TPS61160ADRVT, TPS61160DRVR, and TPS61160DRVT are parametric equivalents of the base product number TPS61160, sharing identical specifications for:

DC-DC regulator topology (Step-Up/Boost)
Input voltage range (2.7V to 18V)
Output voltage (26V)
Switch current rating (700mA)
Operating frequency (600kHz)
PWM dimming capability
Package form factor (6-WSON 2x2)
Thermal and compliance ratings

The differences among substitute parts are limited to packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and product status (all substitutes are Active, whereas the main part is Discontinued). These packaging variations do not affect electrical performance or pin compatibility.

Engineering Selection Recommendations

All four substitute parts (TPS61160ADRVR, TPS61160ADRVT, TPS61160DRVR, TPS61160DRVT) are direct parametric equivalents to the discontinued TPS61160DRVRG4. Selection among these alternatives should be based on:

Product Status: All substitutes maintain Active status, ensuring continued availability and manufacturing support from Texas Instruments.

Compliance & Certifications: All parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL 2 moisture sensitivity ratings, confirming regulatory equivalence for backlight LED driver applications.

Packaging Format: TPS61160ADRVR and TPS61160DRVR are supplied in Cut Tape & Digi-Reel format, while TPS61160ADRVT and TPS61160DRVT are supplied in Tape & Reel format. Selection depends on procurement volume and assembly line requirements.

Inventory Availability: TPS61160DRVR offers the highest stock level (44,100 units), followed by TPS61160ADRVR (17,100 units), TPS61160ADRVT (3,104 units), and TPS61160DRVT (2,140 units).

Frequently Asked Questions (FAQ)

Q: Are all substitute parts pin-compatible with the TPS61160DRVRG4?

A: Yes. All substitute parts use the identical 6-WSON (2x2) package with 6-WDFN exposed pad configuration, ensuring direct pin-for-pin compatibility without PCB redesign.

Q: What is the difference between Cut Tape & Digi-Reel and Tape & Reel packaging?

A: Cut Tape & Digi-Reel format is suitable for smaller production volumes and manual assembly, while Tape & Reel format is optimized for high-volume automated pick-and-place assembly. Both formats contain the same die and electrical specifications.

Q: Can I use any of these substitutes interchangeably in my design?

A: Yes. All four substitute parts are parametric equivalents with identical electrical performance, thermal ratings, and compliance certifications. Selection should be based on packaging format preference and inventory availability.

Q: Why is the original TPS61160DRVRG4 discontinued?

A: The discontinuation reflects normal product lifecycle management by Texas Instruments. The base product number TPS61160 remains in production through the listed substitute part numbers, ensuring design continuity.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. All substitute parts operate across the identical -40°C to 85°C temperature range, maintaining thermal performance for backlight LED driver applications.

Q: Are there any differences in PWM dimming frequency or control between the main part and substitutes?

A: No. All parts operate at 600kHz with PWM dimming capability, providing identical brightness control characteristics for LED backlight applications.
