MAX15014BATX+

Overview

The MAX15014BATX+ is a dual-output power management IC integrating a synchronous buck converter and a low-dropout linear regulator. It operates from an input voltage range of 7.5V to 40V. The switching output provides adjustable voltages from 1.26V to 32V with a maximum current of 1A, while the LDO output delivers fixed 5V at up to 50mA. Operating at a fixed frequency of 135kHz, it utilizes a 36-TQFN (6x6mm) package with an exposed pad for thermal dissipation. The device supports junction temperatures from -40°C to 125°C.

Feature Summary

• Integrates a high-voltage synchronous step-down converter and a separate linear regulator within a single compact package.
• Supports wide input voltage ranges suitable for automotive and industrial bus architectures.
• Provides independent control over switching and linear regulation outputs for mixed-signal power distribution.

Applications

• Automotive infotainment systems requiring isolated noise-sensitive power rails
• Industrial control modules utilizing high-voltage DC buses
• Telecommunications equipment needing combined switching and LDO regulation
