Overview

The NMV1S0505SC is a 1W isolated DC-DC converter module that provides a regulated 5V output from a 4.5V to 5.5V input range. It features 3kVDC isolation in a compact 7-pin SIP package, making it an ideal solution for breaking ground loops and isolating sensitive analog circuitry from digital noise. The internal SMD construction eliminates the need for external components, simplifying power distribution on densely populated boards.

Why Choose This Part

This module offers a high isolation rating of 3kVDC and is UL62368-1 recognized, ensuring compliance with international safety standards. Its design requires no external capacitors or inductors, saving PCB real estate, and it features an industry-standard pinout compatible with several other Murata series like MEV and NMK.

Applications

Ground Loop Elimination
Used to isolate communication interfaces like RS-485 or CAN bus to prevent noise and damage caused by ground potential differences.
Analog Signal Isolation
Provides clean, isolated power to op-amps and ADCs to shield high-precision analog measurements from digital switching noise.
Digital Interface Isolation
Supplies power to the isolated side of digital isolators or optocouplers in industrial control systems.
ITE Power Conversion
Suitable for commercial information technology equipment requiring UL62368-1 recognized safety isolation.

Getting Started

To use this module, simply provide a stable 5V input across the VIN and GND pins and connect the output pins to your isolated load. Ensure that the load does not exceed 200mA and maintain a minimum load of 10 percent to ensure the output remains within regulation limits. No external filtering is required for basic operation, though a small ceramic capacitor can be added to the input to further reduce reflected ripple current.
