What are the key features of LMZ22003TZ/NOPB?
- Non-isolated PoL module with fully integrated inductor and controller delivering 3 A from 0.8 V to 6 V adjustable output
- Wide input voltage range of 6 V to 20 V suits 12 V industrial bus rails and 9 V adapter inputs without derating
- Current-mode PWM control provides superior transient response and cycle-by-cycle overcurrent limiting for robust load protection
What is LMZ22003TZ/NOPB used for?
The LMZ22003TZ/NOPB is targeted at industrial control systems, communications infrastructure, and test equipment that require a compact, high-performance 3 A point-of-load power supply from a 12 V bus. The integrated inductor and controller in a single 7-pin SIP package dramatically reduces design effort and board area compared to discrete solutions. Its adjustable 0.8 V to 6 V output range allows a single device to power multiple logic voltages across different board revisions.

Frequently Asked Questions
What is the adjustable output voltage range of the LMZ22003TZ/NOPB module?
The LMZ22003TZ/NOPB supports an adjustable output voltage from 0.8 V to 6 V, programmable via two external resistors. This flexibility allows a single module to generate core voltages for FPGAs, DSPs, and microcontrollers as well as I/O supply voltages on the same board without requiring different part numbers.
Can the LMZ22003TZ/NOPB be powered from a standard 12 V industrial bus rail?
Yes. The module accepts an input voltage from 6 V to 20 V, making 12 V industrial bus rails an ideal input source. At 12 V input with a 3.3 V output, the module delivers up to 3 A continuously with efficiency well above 80%, reducing heat generation in thermally constrained enclosures.
How does the integrated inductor in the LMZ22003TZ/NOPB simplify board layout versus a discrete regulator?
The module packages the power inductor, controller IC, and bootstrap capacitor into a single 7-pin SIP footprint. This eliminates the need to source, place, and route a separate inductor rated for 3 A, which typically occupies a large area and requires careful coupling management, thereby reducing both component count and PCB size significantly.
What protection features does current-mode control add to the LMZ22003TZ/NOPB?
Current-mode PWM control enables cycle-by-cycle peak current limiting, preventing the inductor current from exceeding a safe threshold on every switching cycle. This inherent overcurrent response protects both the module and downstream load from short-circuit faults without requiring an external current sense resistor or additional protection circuitry.
