LTM4601HVIV#PBF

The LTM4601HVIV#PBF is a high-input-voltage step-down μModule (micromodule) regulator from Analog Devices, integrating a complete DC/DC converter—including the inductor, power MOSFETs, control IC, and compensation network—in a compact LGA surface-mount package. This device accepts a 4.5 V to 28 V input and supplies up to 12 A of continuous output current with an output voltage adjustable down to 0.6 V. The on-board phase-locked loop (PLL) allows the switching frequency to be synchronized to an external clock from 250 kHz to 780 kHz, enabling clean spectral placement in noise-sensitive systems. Output voltage tracking and margining functions support precise sequencing and stress-testing of downstream loads, while integrated soft-start, overcurrent, and overtemperature protection enhance robustness.

Design engineers select the LTM4601HVIV#PBF for high-reliability point-of-load regulation in industrial automation, aerospace, defense, and telecommunications infrastructure where board space is at a premium and thermal performance is critical. Its wide operating junction temperature range of –40 °C to +125 °C (industrial grade) and lead-free finish make it suitable for long-life equipment subjected to harsh environments. Because the μModule architecture eliminates the need to select and route external magnetics and compensation components, it reduces design effort and improves repeatability across production lots. As a current-production Analog Devices module with no announced obsolescence, this part offers a stable supply path for program lifecycles; procurement teams should still monitor product life cycle notifications and ensure alignment with end-application reliability requirements.
