In the realm of power management, achieving high efficiency, compact form factor, and reliable performance is paramount. The **LTM4658IV#PBF** from Analog Devices stands out as a superior solution, addressing these demands with its innovative design. This **µModule (micromodule) regulator** integrates nearly all components required for a complete switching regulator system, simplifying design and accelerating time-to-market for complex applications.
The LTM4658 is exceptionally versatile, capable of being configured as **two independent 25A output regulators or a single 50A output regulator**. This flexibility allows designers to power high-current ASICs, FPGAs, processors, and memory in space-constrained environments like data centers, telecommunications hardware, and test equipment. Its **advanced packaging technology** incorporates power switches, inductors, and support components into a compact 16mm x 16mm x 7.87mm BGA package, effectively minimizing the PCB footprint and mitigating common layout challenges associated with high-current power paths.
A key highlight of this regulator is its **remarkable peak efficiency of up to 92%**. This high efficiency is achieved through optimized internal design and the use of low-loss components, which directly translates to **reduced power dissipation and lower operating temperatures**. This enhances overall system reliability and can eliminate the need for external heat sinks or complex thermal management systems. The module operates over a wide input voltage range of 4.5V to 16V, supporting intermediate bus voltages commonly found in modern systems.
Furthermore, the LTM4658 features a precision reference and remote sense capability, ensuring **excellent DC output accuracy of ±1.25%** across line, load, and temperature variations. Its multi-phase operation, when configured for single-output mode, minimizes input and output ripple current. For system monitoring and control, it includes PMBus-compliant I²C serial interface, enabling telemetry for voltage, current, temperature, and fault reporting.
**ICGOOFind:** The LTM4658IV#PBF is a powerhouse of integration and performance. It delivers an unparalleled combination of **high current density, superior efficiency, and design simplicity**, making it an ideal choice for engineers tackling the most demanding power delivery challenges.
