What are the key features of LM25018MR/NOPB?
- Wide 7.5 V to 48 V input range covers 12 V, 24 V, and 48 V telecom and industrial power rails with a single device
- Adjustable output from 1.225 V enables flexible point-of-load designs without changing the IC
- Voltage-mode control with programmable soft-start reduces inrush current and improves EMI in noise-sensitive environments
What is LM25018MR/NOPB used for?
The LM25018MR/NOPB is designed for industrial control systems, distributed power architectures, and telecom line cards where a 24 V to 48 V input bus must be efficiently stepped down to 1.225 V to 12 V logic or analog supply rails. Its wide input tolerance makes it suitable for battery-backed systems with unregulated bus voltages ranging from 7.5 V to 48 V, including motor drives and building automation controllers. The adjustable output voltage and soft-start feature also make it attractive for laboratory bench power supplies and programmable power modules.

Frequently Asked Questions
What input voltage range does LM25018MR/NOPB support, and which power bus architectures can it serve?
The LM25018MR/NOPB accepts input voltages from 7.5 V to 48 V, covering 12 V, 24 V, and 48 V telecom and industrial power bus standards. This range allows a single device to serve multiple system variants, reducing BOM complexity in multi-rail power architectures.
How low can the LM25018MR/NOPB output voltage be set in adjustable mode?
In adjustable mode, the LM25018MR/NOPB can regulate its output down to 1.225 V reference voltage, enabling point-of-load conversion for low-voltage DSP, FPGA, and microcontroller core supplies. The output is set by an external resistor divider, giving designers flexibility across a wide range of output voltages without changing the IC.
Which industrial applications benefit most from the LM25018MR/NOPB wide input range?
Industrial motor drives, PLC power stages, and building automation systems with 24 V or 48 V bus rails benefit directly from the LM25018MR/NOPB 7.5 V to 48 V input capability. Battery-backed systems where bus voltage can sag to 7.5 V under load or rise to 48 V during charging are also well supported, reducing the need for external input clamping components.
Is LM25018MR/NOPB RoHS compliant, and what does the NOPB suffix indicate?
Yes, the LM25018MR/NOPB is RoHS compliant and fully lead-free. The NOPB suffix explicitly designates No Lead (Pb) in the package finish, confirming it meets JESD-609 Code e3 requirements. The 8-pin SOIC package is processed with a tin-based finish compatible with standard lead-free reflow soldering profiles of 260°C peak.
