TPS92201DRVR Equivalent & Substitute Parts

Part Overview

The TPS92201DRVR is a 5-V, 1 A or 1.5 A high-efficiency LED driver IC manufactured by Texas Instruments. This device functions as a single-output DC-DC step-down (buck) regulator with PWM dimming capability, designed for camera flash applications. The part is currently in active production status with 3474 units available in inventory. Alternative models may be required due to supply constraints, design revisions, or specific application requirements within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS92201DRVR is permissible with parts that maintain identical electrical and mechanical specifications. The critical parameters that determine substitutability are:

• DC-DC regulator topology (Step-Down/Buck configuration)
• Single output channel
• Input voltage range (2.5V to 5.5V minimum and maximum)
• Output voltage range (0.6V to 5.5V)
• Output current capability (1.5A per channel)
• Switching frequency (1.5MHz)
• PWM dimming control method
• Package form factor (6-WDFN Exposed Pad / 6-WSON 2x2)
• Surface mount mounting type
• Operating temperature range (-40°C to 85°C)
• RoHS3 compliance and MSL Level 1 rating

Parts meeting all these criteria are considered parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS92201DRVR and TPS92201ADRVR are active production parts from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability, supply chain considerations, or design revision requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The TPS92201ADRVR currently has 3964 units in stock compared to 3474 units for the TPS92201DRVR, providing additional supply flexibility. Either part is suitable for direct substitution in camera flash LED driver applications without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the TPS92201ADRVR be used as a direct replacement for the TPS92201DRVR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output current ratings, switching frequency, PWM dimming control, package type, and operating temperature range. Direct substitution is permissible without circuit redesign.

Q: Are there any differences in the 6-WSON (2x2) package between these parts?

A: No. Both parts use the identical 6-WDFN Exposed Pad package with 6-WSON (2x2) supplier designation. PCB layout and thermal management considerations remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TPS92201DRVR and TPS92201ADRVR are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: What is the significance of the part number suffix difference (DRVR vs. ADRVR)?

A: The suffix indicates a design revision or production variant within the Texas Instruments product line. Both variants maintain identical functional and electrical specifications for the specified application.

Q: Are there any thermal or performance differences between these substitutes?

A: No performance or thermal differences exist between the parts. Both operate at 1.5MHz switching frequency with 1.5A output current capability and support the full -40°C to 85°C operating temperature range.
