LTM4627IY#PBF

The LTM4627IY#PBF from Analog Devices is a complete high-efficiency step-down DC/DC μModule regulator that integrates the inductor, MOSFETs, and control circuitry inside a compact BGA package. This fully encapsulated design minimizes external component count and PCB layout challenges while delivering 15 A of continuous output current. The device supports a wide input voltage range and provides a single-resistor adjustable output, making it easy to configure for point-of-load rails without complex loop compensation. Built-in protection features include overcurrent, overvoltage, and overtemperature shutdown, ensuring reliable operation in demanding environments. Its current-mode architecture enables fast transient response and straightforward parallel operation for higher power requirements.

Typical applications span telecommunications infrastructure, industrial automation, medical instrumentation, and aerospace power management where board space and reliability are critical. The regulator is frequently used to power FPGAs, ASICs, and microprocessors on densely packed digital boards. The IY suffix designates an industrial temperature grade rating (-40°C to +125°C operating junction range), meeting the needs of extended-environment systems that do not require full military screening. While this part is not a /883 or MIL qualified variant, Analog Devices’ μModule families are manufactured under strict process controls and benefit from long production lifecycles, helping reduce obsolescence risk in high-reliability programs. The #PBF designation confirms lead-free, RoHS-compliant construction suitable for global procurement and compliance standards.
