What are the key features of LM2672N-ADJ?
- Adjustable output voltage set by two external resistors enabling flexible 3.3 V, 5 V, or custom rail design
- 500 mA output current capability suitable for powering microcontrollers and logic circuits from 12 V or 24 V buses
- 6.5 V to 40 V wide input range covering unregulated adapters, automotive, and industrial supply rails
- 260 kHz fixed switching frequency allowing small, low-cost inductors and output capacitors
- 8-pin DIP through-hole package easing prototyping and repair in low-volume industrial equipment
What is LM2672N-ADJ used for?
The LM2672N-ADJ is ideal for low-power embedded systems and industrial control boards that need an adjustable DC-DC buck regulator delivering up to 500 mA from a 6.5 V to 40 V input, such as sensor power supplies, relay driver boards, and PLC I/O modules. Its adjustable output suits laboratory power modules, test fixtures, and prototyping platforms where a 3.3 V, 5 V, or custom voltage rail must be derived from an unregulated 12 V or 24 V bus. The 8-pin DIP package simplifies hand-assembly and field repair in ruggedized industrial equipment and legacy system upgrades.

Frequently Asked Questions
How is the output voltage of the LM2672N-ADJ set, and what voltage range can it cover?
The LM2672N-ADJ output voltage is set by a resistor divider connected to the feedback pin, enabling any output voltage from approximately 1.23 V up to the input supply minus the dropout. With an input from 6.5 V to 40 V, it can generate standard rails like 3.3 V, 5 V, or custom voltages for embedded and industrial circuits.
What is the maximum output current of the LM2672N-ADJ, and which types of loads can it power reliably?
The LM2672N-ADJ delivers up to 500 mA continuous output current, which is sufficient to power 8-bit and 16-bit microcontrollers, CMOS logic ICs, EEPROM modules, low-power sensors, and communication interface circuits in industrial sensor nodes and embedded control boards operating from a 12 V or 24 V supply.
For a 24 V industrial bus application, how does the LM2672N-ADJ switching frequency affect the size of passive components?
The LM2672N-ADJ switches at 260 kHz, allowing the use of inductors in the 68 µH to 150 µH range and ceramic or electrolytic output capacitors below 220 µF, resulting in a compact and low-cost passive filter stage suitable for DIN-rail PLC auxiliary supplies and sensor power regulators running from a 24 V industrial bus.
When is the LM2672N-ADJ in an 8-pin DIP package preferred over an SMD alternative for prototype or low-volume production?
The 8-pin DIP package of the LM2672N-ADJ allows direct insertion into breadboards and prototype PCBs without SMD soldering equipment. This makes it preferable for laboratory test rigs, field repair scenarios, and low-volume industrial applications where hand assembly or component substitution must be straightforward, while still delivering 500 mA from 6.5 V to 40 V input.
