Analog Devices Inc./Maxim Integrated MAX16992EVKIT#

Overview

MAX16992EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit for the MAX16992 automotive current-mode boost controller, designed to demonstrate 16W front-end preboost functionality in automotive systems. It operates from 4.5V (3V in bootstrapped mode) to 36V input, delivers regulated 8V/2A output, supports external clock synchronization up to 2.5MHz, withstands 42V load-dump for 400ms, and integrates fault protection including cycle-by-cycle current limit, hiccup mode, and thermal shutdown.

For engineers reviewing the MAX16992EVKIT# datasheet, MAX16992EVKIT# pinout, MAX16992EVKIT# application, or MAX16992EVKIT# equivalent, this page provides verified hardware configuration details, jumper-based operational modes (enable, bootstrap, reference selection), two-phase synchronization setup, proven PCB layout guidance, and test-proven performance boundaries for automotive preboost validation.

Technical Context

The MAX16992EVKIT# implements a complete 2.2MHz fixed-frequency current-mode boost converter using the MAX16992ATCE/V+ controller in 12-pin TQFN-EP package, with integrated low-side FET driver and internal 1V FB reference. It features configurable operation via three onboard jumpers (JU1 for enable, JU2 for bootstrap mode, JU3 for internal/external reference selection).

Hardware-level demonstration includes dynamic output-voltage adjustment via REFIN, PGOOD flag monitoring, external p-MOSFET (P1) for output disconnect during fault, and dual-phase coordination support through COMP and SYNCO signal routing between master/slave boards - all validated under automotive-grade voltage stress (42V/400ms load dump) and thermal conditions.

FAQ

What is the primary function of the MAX16992EVKIT#?

The MAX16992EVKIT# is an evaluation kit for the MAX16992 automotive boost controller, providing a fully assembled and tested platform to validate 8V/2A preboost operation in automotive front-end power systems. It demonstrates key features including 2.2MHz switching, external clock sync (1–2.5MHz), bootstrapped low-input operation (down to 3V), and fault protections like hiccup mode and thermal shutdown - all implemented on a production-grade PCB layout.

Does the MAX16992EVKIT# support dual-phase operation?

Yes, the MAX16992EVKIT# supports two-phase configuration when used with a second identical board. The master EV kit routes COMP and SYNCO signals to the slave unit via BNC cable and PCB pads, enabling synchronized interleaved operation. This reduces input/output ripple and improves thermal distribution - critical for higher-power automotive preboost implementations beyond 16W.

How do I configure the MAX16992EVKIT# for bootstrapped mode?

To configure the MAX16992EVKIT# for bootstrapped mode, install the shunt on pins 2–3 of jumper JU2. This connects the SUP pin to VOUT, allowing the controller to self-power from the regulated 8V output and maintain regulation even when input drops to 3V - essential for automotive cold-crank scenarios where battery voltage sags below 4.5V.

Can the output voltage of the MAX16992EVKIT# be adjusted dynamically?

Yes, the MAX16992EVKIT# supports dynamic output-voltage adjustment by removing the shunt from jumper JU3 and applying an external analog voltage to the REFIN pin. The applied voltage becomes the feedback reference, enabling real-time tuning of the regulated output - useful for testing variable-rail loads or adaptive power sequencing in automotive ECUs.

What protection features are demonstrated on the MAX16992EVKIT#?

The MAX16992EVKIT# demonstrates cycle-by-cycle current limiting, hiccup-mode fault recovery, thermal shutdown, and a PGOOD flag indicating valid output regulation. It also includes an external p-MOSFET (P1) that disconnects the boost output from the load during overcurrent or thermal faults - a safety-critical feature required for ASIL-B compliant automotive power designs.
