Linear Technology's LTM4611EV#PBF - A High-Efficiency, Low-Profile uModule Regulator

The LTM4611EV#PBF is a high-performance, easy-to-use uModule (micromodule) regulator from Linear Technology, now part of Analog Devices. This innovative product is designed to meet the needs of space-constrained applications requiring efficient power conversion. The LTM4611EV#PBF is a complete system-in-a-package that includes the switching controller, power FETs, inductor and all support components in a compact, surface-mount LGA package.

This micromodule regulator operates over an input voltage range from 4.5V to 28V and provides an adjustable output voltage from 0.8V to 5V, which can be set by a single external resistor. With its high efficiency and power density, the LTM4611EV#PBF is an ideal solution for applications in telecommunications, industrial, and medical equipment, as well as military and aerospace systems where performance and reliability are critical.

One of the key features of the LTM4611EV#PBF is its ability to deliver up to 10A of continuous output current with no heat sink, and up to 14A with adequate airflow and heat sinking. This capability, combined with its low-profile design (measuring just 15mm x 15mm x 2.82mm), makes it a versatile choice for systems where space is at a premium and thermal management is a concern.

The device also boasts robust protection features, including overvoltage, overcurrent, and over-temperature protection, ensuring reliable operation under a range of fault conditions. Additionally, the LTM4611EV#PBF supports frequency synchronization and tracking, which allows multiple units to operate in parallel for higher current applications while minimizing noise and potential interference.

With its comprehensive feature set, the LTM4611EV#PBF exemplifies Linear Technology's commitment to providing innovative power solutions that simplify design, reduce component count, and improve system reliability. Whether you're designing a new system or upgrading an existing one, the LTM4611EV#PBF offers a combination of performance, convenience, and reliability that is hard to match.
