Key Features
- Integrated inductor in a 7-pin power module delivers 3 A output current with 6 V to 42 V wide input range
- Adjustable output voltage from 0.8 V to 6 V using constant on-time voltage-mode control for fast transient response
- RoHS-compliant lead-free construction reduces external component count for rapid power supply prototyping
Applications
The LMZ14203EXTTZE/NOPB is designed for industrial equipment, communications infrastructure, and test instruments that require a compact and efficient step-down power supply from a wide input voltage rail. Its built-in inductor eliminates the most space-consuming external component, enabling engineers to achieve a complete 3 A DC-DC converter in a minimal PCB footprint. The 42 V maximum input supports direct conversion from 24 V industrial bus or unregulated adapter supplies to processor and logic core voltages.

Frequently Asked Questions
What input voltage range does LMZ14203EXTTZE/NOPB support and which industrial supply rails is it compatible with?
The LMZ14203EXTTZE/NOPB accepts input voltages from 6 V to 42 V, making it directly compatible with 12 V, 24 V, and 36 V industrial supply rails. This wide range allows a single regulator design to cover multiple system variants without hardware changes, simplifying inventory management in industrial automation and motor drive equipment.
How does the integrated inductor in LMZ14203EXTTZE/NOPB reduce PCB design complexity?
The LMZ14203EXTTZE/NOPB integrates the power inductor inside the module package, eliminating the largest and most difficult-to-place external component in a typical step-down converter. Designers only need to add input and output capacitors plus two resistors for voltage setting, reducing total solution size by approximately 50% compared to a discrete 3 A buck converter design with an external inductor.
What output voltage range can be set on LMZ14203EXTTZE/NOPB and how is it adjusted?
The LMZ14203EXTTZE/NOPB supports adjustable output voltage from 0.8 V to 6 V, set by a resistor divider between the feedback pin and ground. This range covers common logic supply voltages including 1.0 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V, making a single module design adaptable to processor cores, memory interfaces, and peripheral power rails.
Which control method does LMZ14203EXTTZE/NOPB use and how does it affect transient response?
The LMZ14203EXTTZE/NOPB employs constant on-time voltage-mode control, which responds to load transients within a single switching cycle by immediately adjusting the on-time duty cycle. This technique delivers fast load transient recovery without a complex error amplifier compensation network, simplifying loop stability design while maintaining tight output voltage regulation for noise-sensitive digital loads up to 3 A.
