Overview
The LMZM23600V5SILT is a 36-V, 0.5-A step-down DC/DC power module produced by Texas Instruments. This integrated-inductor power module is specifically designed for space-constrained industrial applications. It offers a wide operating input voltage range of 4 V to 36 V and is available in fixed output voltage options of 5 V and 3.3 V, as well as an adjustable output voltage option ranging from 1.2 V to 15 V. The module is highly integrated, requiring only two external components (input and output capacitors) for a 5-V or 3.3-V output design, making it extremely easy to use and optimize for performance-driven and low EMI industrial applications.
