The LTM4641EY#PBF is a state-of-the-art power management solution from Linear Technology, now part of Analog Devices, designed to cater to the needs of space-constrained applications without compromising on performance. This innovative product is a complete system-in-package (SiP) that integrates a quad output step-down DC/DC μModule (micromodule) regulator with switching controllers, power FETs, inductors, and all the supporting components in an ultra-thin LGA package.

Key Features:

• Compact Design: The LTM4641EY#PBF comes in a low profile (1.82mm) over-molded Land Grid Array (LGA) package (15mm x 15mm) that ensures a minimal footprint on the PCB, making it ideal for systems with limited space.
• High Efficiency: This μModule regulator is designed for high efficiency, with a wide input voltage range from 3.1V to 20V and an output voltage range from 0.6V to 5.5V, making it versatile for various applications.
• Quad Output Channels: It features four high-performance buck regulators that can deliver up to 4A of continuous output current each, providing a total solution for multiple voltage rails in a system.
• Configurable: The outputs can be paralleled for higher current capability, or they can be set up to power different voltage levels, offering design flexibility.
• Advanced Thermal Management: The LTM4641EY#PBF has excellent thermal performance due to its over-molded construction, which allows for effective heat dissipation.
• Protection Features: It includes overvoltage, overcurrent, and over-temperature protection for enhanced reliability and longevity of the application.

Applications:

The LTM4641EY#PBF is ideal for use in a wide range of applications, including telecommunications, networking, industrial systems, and aerospace, where power efficiency and space savings are critical. Its ability to provide multiple regulated outputs with high efficiency and reliability makes it a versatile solution for powering FPGAs, ASICs, microprocessors, and other digital ICs.

With the LTM4641EY#PBF, designers can simplify their power supply design, reduce the number of external components, and accelerate time-to-market for their products.
