Product details
Overview
MAX17672FATB+ from Analog Devices is a high-voltage power-management IC combining a 150mA synchronous step-down DC/DC converter with a 50mA linear regulator. The device is designed for compact industrial, automotive, building automation, and distributed power systems that need a high-voltage input regulator plus a small auxiliary linear rail.
As part of the MAX17670-MAX17672 product family, MAX17672FATB+ combines 4V to 60V input operation, synchronous buck conversion, a 50mA linear regulator, RESET output, high-efficiency light-load behavior, and a compact LFCSP package. For engineers reviewing the MAX17672FATB+ datasheet, MAX17672FATB+ pinout, MAX17672FATB+ application, or MAX17672FATB+ equivalent, this device is widely used in industrial sensors, building automation nodes, automotive auxiliary supplies, high-voltage embedded modules, PLC I/O systems, and distributed control electronics.
Technical Context
In high-voltage embedded systems, MAX17672FATB+ operates as a front-end synchronous buck regulator accepting 4V to 60V inputs and generating a low-current regulated rail. Its integrated LDO provides an additional 50mA output for bias or auxiliary circuitry.
The architecture is useful for systems powered from 12V, 24V, 48V, or transient-prone industrial buses where a compact primary regulator and auxiliary linear output reduce external component count.
MAX17672FATB+ is commonly used where high input voltage, RESET supervision, low quiescent current, compact LFCSP packaging, and EMI-conscious power conversion are required.

Pinout & Package
The MAX17672FATB+ pinout includes high-voltage input, buck switch node, output/feedback functions, linear regulator input/output, RESET output, enable/control pins, and exposed-pad ground.
For PCB design, the high-voltage input capacitor, inductor, and output capacitor should be placed close to the buck pins, while the LDO output and RESET routing should be separated from switching noise.

Equivalent & Alternatives
When evaluating a MAX17672FATB+ equivalent, engineers should compare input-voltage range, buck current, LDO current, RESET function, package, quiescent current, and EMI requirements.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17671FATB+ | Analog Devices related high-voltage buck-plus-LDO device with different output/current option details. | Used in similar industrial high-voltage low-current rails. | Compare output configuration, package, and current requirements. |
| LM5164DDAR | Texas Instruments wide-input synchronous buck converter without the same integrated LDO structure. | Used in industrial high-voltage buck applications. | Compare LDO need, input range, output current, and package. |
Compared with MAX17671FATB+, MAX17672FATB+ should be selected when its ordering option and output configuration match the design. MAX17672FATB+ vs LM5164DDAR selection depends on whether the system needs an integrated 50mA LDO, RESET output, current rating, and LFCSP footprint.
Quality
MAX17672FATB+ should be sourced as original Analog Devices components through traceable supply channels. Quality checks may include LFCSP package inspection, top-mark validation, solderability testing, output-voltage verification, and regulator load testing.
Production validation should include startup behavior, load transients, thermal performance, protection response, output ripple, and PCB layout review for the switching and linear regulator sections.
