What is LMZ12003TZX-ADJ/NOPB used for?
LMZ12003TZX-ADJ/NOPB is widely used as a point-of-load (POL) converter on boards powered from a 12 V bus, supplying processor cores, FPGAs, DDR memory, and I/O rails at voltages from 0.8 V to 6 V with up to 3 A of current. The integrated inductor module eliminates the need for external magnetics, significantly reducing design time, PCB layout complexity, and the risk of EMI from improper inductor placement. It is also applied in test equipment, network switches, and industrial controllers where a compact, self-contained regulated supply is preferred over a discrete buck converter.

Frequently Asked Questions
What output voltage range and maximum output current does LMZ12003TZX-ADJ/NOPB support for FPGA core power?
LMZ12003TZX-ADJ/NOPB provides an adjustable output from 0.8 V to 6 V at up to 3 A continuous output current, covering the core voltage requirements of most FPGAs, including 1.0 V, 1.2 V, and 1.8 V rails, from a single module without an external inductor.
How does the integrated inductor inside the TO-PMOD module simplify PCB layout compared to a discrete buck converter?
Because the inductor is embedded within the module package, designers do not need to route high-frequency switched current loops on the PCB. This eliminates the main source of radiated EMI in a discrete buck design, reduces the number of components to 3 to 4 passive parts, and can shrink the overall power supply footprint by more than 50%.
Can LMZ12003TZX-ADJ/NOPB operate directly from a 12 V input rail, and what is its absolute maximum input voltage?
Yes. The nominal input voltage is 12 V, which falls within the specified 4.5 V to 20 V operating range. The absolute maximum input voltage is 20 V, so a well-regulated 12 V bus with typical transient spikes remains safely within the device's ratings without additional clamping.
What are the RoHS and lead-free status implications of the NOPB suffix for procurement and compliance documentation?
The NOPB suffix confirms that LMZ12003TZX-ADJ/NOPB uses a tin-silver-copper (SAC) lead-free solder finish with no added lead, making it fully RoHS-compliant and suitable for export to the EU, China, and other jurisdictions requiring REACH and RoHS conformance in component procurement records.
