LTM4615IV#PBF

The LTM4615IV#PBF from Analog Devices is a triple-output DC/DC µModule regulator that integrates dual 4A step-down switching converters and a single 1.5A very low dropout (VLDO) linear regulator into a compact land grid array (LGA) package. This complete system-in-package solution incorporates the inductors, power MOSFETs, DC/DC controllers, and compensation networks internally, minimizing external component count and simplifying printed circuit board layout. Typical of the µModule family, the device offers predictable, high-efficiency performance across a wide input voltage range and maintains excellent output regulation under transient load conditions, critical for dense power distribution networks.

Engineers deploy this regulator extensively in industrial automation, aerospace, defense, and high-reliability instrumentation systems that demand multiple low-voltage rails with fast transient response and low noise. It effectively powers FPGAs, ASICs, microprocessors, and data converters in embedded computing, test and measurement equipment, radar processing units, and secure communication platforms. The “I” suffix denotes an industrial operating temperature range of -40°C to +125°C, making it suitable for ruggedized environments, while the lead‑free (PBF) plating ensures RoHS compliance. For procurement and design teams, this part represents a fully validated, single‑component power solution that reduces design‑in time and bill‑of‑materials complexity. Backed by Analog Devices’ long‑lifecycle product policy, it presents a low obsolescence risk and is supported by robust supply chain continuity, an important factor for programs requiring extended production sustainment.
