Analog Devices Inc./Maxim Integrated MAX17014EVKIT+

Overview

MAX17014EVKIT+ from Maxim Integrated is an evaluation kit for the MAX17014 multiple-output power-supply controller, designed to generate all supply rails for TFT LCD panels in TVs and monitors operating from a regulated 12V input. It integrates step-down/step-up regulators, dual charge pumps, two high-current op amps (±150mA, 100V/µs slew rate), and logic-controlled high-voltage switches - enabling full-panel power sequencing and VCOM driving.

For engineers reviewing the MAX17014EVKIT+ datasheet, MAX17014EVKIT+ setup guide, MAX17014EVKIT+ test procedures, or MAX17014EVKIT+ compatibility with MAX17014ETM+, this kit provides validated reference design, configurable timing control, fault-latch diagnostics, and complete hardware support for evaluating power-up sequencing, gate driver voltage generation, and VCOM amplifier performance under real LCD panel load conditions.

Technical Context

The MAX17014EVKIT+ implements the full functional architecture of the MAX17014 IC, including independent 600kHz/1.2MHz selectable-frequency current-mode step-down (LX2) and step-up (LX1) regulators with internal 120mΩ/110mΩ MOSFETs, adjustable ± charge-pump outputs (POS1/NEG1, POS2/NEG2), and Dual Mode™ high-voltage switch control (GON/DRN/SRC) with programmable delay via DEL1/DEL2 pins.

It supports full evaluation of the integrated ±150mA rail-to-rail op amps driving LCD backplane (VCOM), AVDD sequencing via internal p-channel FET, soft-start (3ms), fault latch (50ms trigger, 160ms restart), and thermal shutdown at +160°C - all operating across –40°C to +85°C ambient with 48-pin thin QFN packaging.

FAQ

What is the primary function of the MAX17014EVKIT+?

The MAX17014EVKIT+ is an evaluation kit for the MAX17014 power-supply controller IC. It enables full hardware validation of the IC's ability to generate all required voltages for TFT LCD panels-including step-down, step-up, positive/negative charge-pump outputs, VCOM-driving op amps, and high-voltage gate driver sequencing-under real-world 12V-input conditions. The MAX17014EVKIT+ includes populated circuitry, test points, jumpers, and documentation aligned with the MAX17014ETM+ datasheet.

Does the MAX17014EVKIT+ support configurable power-up timing?

Yes, the MAX17014EVKIT+ fully supports adjustable power-up sequencing via DEL1 and DEL2 pins, which control timing delays for AVDD and gate driver outputs (GON/GOFF). These pins accept external RC networks to set precise startup intervals, allowing engineers to validate timing margins for LCD panel initialization. The MAX17014EVKIT+ schematic and user guide provide recommended component values and layout guidance for reproducible sequencing behavior matching the MAX17014ETM+ specification.

Can the MAX17014EVKIT+ be used to evaluate VCOM amplifier performance?

Yes, the MAX17014EVKIT+ directly supports evaluation of both integrated VCOM op amps (OUT1/OUT2) with full access to POS1/POS2, NEG1/NEG2, and OVIN pins. It enables measurement of key parameters including ±150mA short-circuit current, 100V/µs slew rate, 20MHz bandwidth, rail-to-rail input/output swing, and load-transient response - all under actual panel-capacitive loading conditions. The MAX17014EVKIT+ board includes dedicated test points and bypass provisions to isolate amplifier performance from regulator noise.

What protection features can be verified using the MAX17014EVKIT+?

The MAX17014EVKIT+ allows verification of overcurrent, overvoltage, undervoltage, and thermal protection mechanisms built into the MAX17014ETM+. This includes step-up/step-down current-limit tripping (3.2A/3.7A typical), SUP/SWI/OVIN overvoltage lockout (18–20V thresholds), VIN/VL UVLO (6.5V/3.9V), fault latch timing (50ms detection, 160ms restart), and thermal shutdown (+160°C). All protections are implemented per the MAX17014ETM+ silicon and can be triggered and observed via onboard test points and status LEDs.

Is the MAX17014EVKIT+ compatible with standard 12V lab supplies?

Yes, the MAX17014EVKIT+ is designed for direct connection to a regulated 12V DC lab supply (8V–16.5V input range), with reverse-polarity and overvoltage protection on the input connector. It requires no auxiliary supplies - all internal rails (VL, REF, AVDD, OVIN, SUP) are generated from the single 12V input. The MAX17014EVKIT+ user guide specifies minimum current capability (≥3A), ripple limits (<50mVpp), and grounding recommendations to ensure stable operation during MAX17014ETM+ evaluation.
