What are the key features of LM34930TL?
- Current-mode control topology with 8 V to 33 V input range covering wide-input industrial and automotive power rails
- Adjustable output voltage starting from 2.5 V, enabling flexible point-of-load regulation from a single 12 V nominal bus
- Compact 12-ball BGA package minimizing board footprint for space-constrained power supply designs
What is LM34930TL used for?
The LM34930TL is designed for step-down DC-DC conversion in industrial control systems, telecom equipment, and automotive subsystems powered from 12 V or 24 V rails. Its current-mode control provides fast transient response and inherent cycle-by-cycle current limiting, improving reliability under variable load conditions. The adjustable output from 2.5 V makes it versatile for generating multiple logic supply rails from a single input.

Frequently Asked Questions
What input voltage range does the LM34930TL support, and which power rail standards does it cover?
The LM34930TL accepts input voltages from 8 V to 33 V, covering common industrial 12 V and 24 V bus standards as well as automotive 12 V battery rails that can surge to 28 V during load dump. This wide input range allows a single design to be reused across multiple end products without changing the power stage.
How does the LM34930TL's current-mode control benefit power supply stability under rapidly changing loads?
Current-mode control samples inductor current every switching cycle, giving the LM34930TL inherent cycle-by-cycle current limiting and faster line transient response compared to voltage-mode regulators. This reduces output voltage deviation during load steps in processor core power supplies and motor drive gate drivers, where load current can change by several amperes within microseconds.
What is the minimum adjustable output voltage, and how is it set?
The LM34930TL output is adjustable down to 2.5 V using an external resistor divider from the output rail to the feedback pin. This allows designers to generate standard logic supply voltages such as 3.3 V or 5 V from a 12 V input with a simple two-resistor network, without the need for a fixed-output variant or additional linear post-regulator.
What are the lead-free and RoHS compliance considerations when ordering the LM34930TL for consumer applications?
The LM34930TL carries a non-RoHS (Pb-containing) designation based on its JESD-609 e0 code, meaning the package finish includes lead. Designers targeting RoHS-compliant products for EU or consumer markets should confirm end-of-life status and check for a lead-free alternative part number before placing volume orders, as the YTEOL indicator shows this part may be approaching end of production.
