Overview

The LMZ31506HRUQT is a 6A power module that integrates a DC/DC converter, shielded inductor, and passives into a low-profile QFN package. It operates from an input voltage range of 4.5V to 14.5V and provides an adjustable output from 1.2V to 5.5V with up to 96 percent efficiency.

Why Choose This Part

The module simplifies PCB layout by integrating the power inductor and requiring as few as five external components. It offers advanced power management features including programmable UVLO, output voltage sequencing, and a power good signal for system monitoring.

Applications

High-Density Point-of-Load Regulators
Ideal for space-constrained designs requiring 6A of current with minimal external components due to the integrated inductor.
FPGA and DSP Power Rails
Provides the 1 percent reference accuracy and sequencing capabilities required for modern high-performance processors.
Broadband and Communications Infrastructure
The adjustable switching frequency (480 kHz to 780 kHz) and external clock synchronization help manage EMI in sensitive RF and data environments.
