Product Overview
LTM4608IV#PBF is an 8A high-efficiency step-down DC/DC μModule regulator from ADI. It works with 2.7V–5.5V input and adjustable 0.6V–5V output via one resistor. This all-in-one LGA-68 package integrates controller, MOSFET, inductor and compensation circuits to simplify PCB design. It supports frequency sync, voltage tracking and power sequencing. Industrial grade for -40°C ~ +85°C ambient temp, max junction temp 125°C for stable harsh-environment operation.
Core Advantages
All-In-One Power Solution
Integrates full power loop components inside one package, cuts PCB layout workload and shortens product development cycle.
Mini Low-Profile Package
Compact 9mm×15mm×2.82mm LGA-68 form factor, fits double-sided high-density circuit boards.
Great Heat Dissipation
LGA packaging reduces thermal resistance to PCB; delivers full 8A continuous output without extra heat sinks under normal use.
EMI Reduction & Multi-Rail Control
External clock synchronization lowers system EMI; supports voltage tracking for accurate multi-power supply startup sequencing.
