Frequently Asked Questions

What is the input voltage range of the LM2670S-12?

The LM2670S-12 accepts an input voltage from 15V to 40V, with a nominal operating voltage of 24V. This wide range makes it suitable for industrial 24V bus systems and automotive 12V–36V battery rails that may fluctuate under load.

What output voltage does the LM2670S-12 regulate to?

The LM2670S-12 is factory-set to a fixed 12V output voltage. It uses voltage-mode pulse width modulation (PWM) control to maintain tight regulation, making it ideal for systems that require a precise 12V supply from a higher-voltage input bus.

What package does the LM2670S-12 come in?

The LM2670S-12 is available in a 7-lead R-PSSO surface-mount package (JESD-30 code: R-PSSO-G7). This compact package provides good thermal performance and is well-suited for space-constrained PCB designs in industrial and embedded applications.

What are typical applications for the LM2670S-12?

Typical applications include industrial 24V to 12V step-down converters, automotive accessory power supplies, telecom equipment power rails, and embedded system boards. Its Simple Switcher architecture reduces the number of external passive components required, speeding up design and reducing BOM cost.

Is the LM2670S-12 a lead-free (RoHS-compliant) component?

Based on available data, the LM2670S-12 carries a Pbfree Code of 'No', indicating it may not be a lead-free version. Designers working on RoHS-compliant products should verify the specific date code or contact Texas Instruments for the latest compliance status before purchasing.
