Overview
The LMZM23600SILR, produced by Texas Instruments, is a 36-V, 0.5-A step-down DC/DC power module designed specifically for space-constrained industrial applications. This integrated-inductor power module offers a wide input voltage range of 4 V to 36 V and is available in adjustable and fixed output voltage options. The device is highly integrated, requiring only two external components (input and output capacitors) for 5-V or 3.3-V output designs, making it ideal for applications where board space is limited.
