The LTM4600 is a high-efficiency DC/DC µModule with a 10A output current and an output voltage range of 0.6V to 5V. It features a high-efficiency design that does not require heat sinks or airflow to meet power specifications, and it has a fast transient response and fault protection features.
The LTM4600 is a 10 A, non‑isolated synchronous step‑down DC/DC power module designed for point‑of‑load regulation. It operates from a wide input range of 4.5 V to 20 V and delivers an adjustable output voltage from 0.6 V to 5 V, with up to 92 % efficiency and 1.5 % regulation accuracy. The module integrates the switching controller, power FETs, inductor and all required support components in a compact 15 mm × 15 mm × 2.8 mm LGA package.
Typical applications include telecom, networking, servers and industrial equipment. The datasheet details electrical characteristics, absolute maximum ratings, pin assignments, decoupling requirements, protection features and a simplified block diagram to aid designers in implementing the LTM4600 in their systems.
