Is there a pin-compatible replacement for TPS61170DRVR?

Based on the reviewed candidates, no pin-compatible replacement has been identified. The target's 2x2mm QFN package and 1.2MHz frequency are specific, making direct drop-in substitutes rare.

What risks should I check before replacing TPS61170DRVR?

Key risks include package and pinout incompatibility requiring a new PCB layout. Also, check the switching frequency, as a lower frequency will require larger external inductors and capacitors, affecting board space and performance.

TPS61170DRVR Alternatives, Datasheet & Cross Reference | Texas Instruments

TPS61170DRVR is a high-voltage boost/SEPIC converter from Texas Instruments in a compact 2x2mm QFN package. Finding a direct, pin-compatible replacement is challenging due to its specific combination of high frequency and small footprint.

AI replacement insight

Package riskhigh

Candidate has a different package (SO-8 vs QFN) and pin count, requiring a new PCB layout.

Electrical riskmedium

The much lower switching frequency requires recalculation and replacement of external components like the inductor.

Firmware risklow

These components are hardware-configured and do not typically involve firmware.

Can it be replaced directly?

No, there are no direct, pin-compatible replacements for TPS61170DRVR among the candidates reviewed. All require significant design changes.

Best replacement path

The best path is a functional alternative like AZ34063UMTR-G1, which requires a full redesign. No drop-in replacements were found.

Main risk

The main risk is the need for a complete PCB redesign due to package, pinout, and switching frequency differences.

Recommended alternatives

A functional alternative that can be configured as a boost converter, but requires significant redesign.
