LTM4601/LTM4601-1 is a 12A DC/DC µModules with PLL, output tracking, and margining. It is suitable for telecom and networking equipment, servers, industrial equipment, point of load regulation, and complete switch mode power supply. It features a wide input voltage range, parallel multiple µModules for current sharing, differential remote sensing, PLL frequency synchronization, ±1.5% regulation, and current foldback protection.
The LTM4601 and LTM4601-1 are compact 12 A step‑down DC/DC modules housed in a 15 mm × 15 mm × 2.8 mm LGA package. They operate from a wide input voltage range and provide selectable output voltages from 0.6 V to 5 V, making them suitable for point‑of‑load regulation in telecom, networking, server and industrial equipment.
Key features include high efficiency (up to 95 % at 5 V output), programmable soft‑start, output voltage tracking, margining, PLL synchronization, and a differential remote‑sense amplifier (available on the LTM4601 but not on the LTM4601-1). The device offers current foldback protection, over‑voltage protection, and a low‑profile footprint for high‑density board designs.
