‘LTM4600 DC/DC μmodule regulator thermal performance’ - .PDF file.

The LTM4600 DC/DC μmodule regulator from Linear Technology is a complete high-power density stepdown regulator for 10A continuous (14A peak) loads. The purpose of this thermal application note is to provide a guideline for using the μmodule regulator in ambient environments with or without air flow. The goal is to measure the temperature of a design, derive thermal models for different cases and finally determine the junction-to-ambient thermal resistance (qJA) in units of °C/W in the heat path. The data includes power loss curves, safe operating curves (SOA), thermal camera images and current derating curves verses ambient temperature with and without a heatsink. The influence of air flow is also included in the derating curves. The 24V designs are analysed for a worse case temperature rise due to the lower efficiency exhibited in these higher input voltage designs.
