Analog Devices Inc./Maxim Integrated MAX17292ETCC+T

Overview

MAX17292ETCC+T from Maxim Integrated is a high-efficiency, synchronous step-up DC-DC controller optimized for wide-input industrial and automotive power supplies. It operates from 4.5V to 36V input (extendable to 2.5V in bootstrapped mode), delivers up to 2.5MHz switching frequency, features 4µA shutdown current, 5V internal PVL regulator, and 42V input transient protection. It is used in telecom hardware and distributed supply regulation where compact, high-frequency boost conversion is required.

For engineers reviewing the MAX17292ETCC+T datasheet, MAX17292ETCC+T pinout, MAX17292ETCC+T application, or MAX17292ETCC+T equivalent, key selection criteria include its 1MHz–2.5MHz programmable oscillator range, OVP-enabled overvoltage protection, REFIN-based on-the-fly output adjustment, and TQFN-12 (3mm × 3mm) package with exposed thermal pad.

Technical Context

The MAX17292ETCC+T implements constant-frequency peak current-mode PWM control with programmable slope compensation to prevent subharmonic oscillation above 50% duty cycle. Its internal 5V PVL regulator powers the gate driver and enables direct operation from automotive battery inputs.

It supports external synchronization via FSET/SYNC (1MHz–2.5MHz range), provides 180° out-of-phase SYNCO output for multiphase designs, and integrates hiccup-mode protection triggered after 16 consecutive current-limit events - all while maintaining <4µA shutdown current and spread-spectrum EMI reduction in D/F versions.

FAQ

What is the maximum switching frequency supported by MAX17292ETCC+T?

The MAX17292ETCC+T supports a maximum switching frequency of 2.5MHz when configured with an appropriate resistor on the FSET/SYNC pin or synchronized to an external 2.5MHz clock signal. This high-frequency capability enables miniaturized inductors and ceramic-only output filtering, critical for space-constrained telecom and automotive applications where the MAX17292ETCC+T is deployed.

Does MAX17292ETCC+T include overvoltage protection, and how is it implemented?

Yes, MAX17292ETCC+T includes dedicated overvoltage protection via the OVP pin. When the voltage at OVP exceeds 110% of the FB regulation voltage, switching is disabled; operation resumes when OVP falls below 107.5% of FB. This feature is implemented using an internal comparator and is active in C/D/F versions like MAX17292ETCC+T - enabling precise, adjustable output fault detection without external circuitry.

Can MAX17292ETCC+T operate from a 2.5V input supply?

Yes, MAX17292ETCC+T can operate from as low as 2.5V input in bootstrapped mode, where the output supplies the SUP pin. This mode bypasses the standard 4.5V minimum input requirement and is enabled by connecting the output to SUP through appropriate isolation. The MAX17292ETCC+T's internal 5V PVL regulator remains functional in this configuration, sustaining gate drive and internal logic - making it suitable for cold-crank automotive scenarios.

What package type and thermal characteristics does MAX17292ETCC+T use?

MAX17292ETCC+T uses a 12-pin TQFN package (3mm × 3mm, 0.5mm pitch) with exposed thermal pad (EP). On a four-layer PCB, its junction-to-ambient thermal resistance is 68°C/W and junction-to-case is 11°C/W. These values enable reliable operation up to +85°C ambient when the EP pad is properly soldered to a large copper ground plane - a key design requirement for sustained 2.5MHz boost operation in the MAX17292ETCC+T.

How does the MAX17292ETCC+T achieve reduced EMI performance?

The MAX17292ETCC+T reduces EMI through two integrated methods: spread-spectrum modulation (in D/F versions) that dithers the switching frequency by ±6%, and a high 2.5MHz fundamental frequency that pushes noise energy beyond sensitive bands. Both features are inherent to the MAX17292ETCC+T silicon design and require no external components - simplifying EMC compliance in dense PCB layouts common in telecom and industrial equipment.
