Product Overview: LTM4628IY from Linear Technology

The LTM4628IY is a high-performance micro-module (µModule) regulator from Linear Technology, designed with advanced power management features to cater to a wide range of applications. This compact, efficient, and versatile power solution is ideal for systems that require a small footprint without sacrificing performance.

At the heart of the LTM4628IY is a dual 8A or single 16A output step-down DC/DC regulator, which operates over an input voltage range of 3.1V to 20V. This makes it suitable for a variety of voltage sources, from multi-cell batteries to intermediate bus voltages. Its output voltage is adjustable from 0.6V to 5.5V, which can be precisely set to meet the needs of modern low-voltage, high-current digital ICs such as FPGAs, ASICs, microprocessors, and DSPs.

The module incorporates key features such as power good indicators, on-board DC/DC controllers, power switches, inductors, and support components, all within a compact 15mm × 15mm × 4.92mm LGA package. This level of integration simplifies design and reduces time-to-market, as it minimizes the need for external components and complex layout challenges.

The LTM4628IY also boasts advanced thermal performance, thanks to its over-molded construction, which enhances heat dissipation and allows for operation in high temperature environments. In addition, the device supports frequency synchronization, multiphase operation, Burst Mode® operation for improved efficiency at light loads, and tracking for sequencing in complex power systems.

With its robust design, the LTM4628IY provides protection features that include overvoltage, overcurrent, and over-temperature protection, ensuring reliable operation under adverse conditions. It is RoHS compliant and designed for automated assembly by standard surface mount equipment.

Whether for telecommunications, networking, industrial, or computing applications, the LTM4628IY from Linear Technology offers a powerful, efficient, and reliable solution for today's demanding power supply requirements.
