The MAX1724EZK50-T is a synchronous buck DC-to-DC converter providing up to 54A of continuous output current. This integrated PMIC (Power Management Integrated Circuit) operates across a wide input voltage range of up to 32V, and provides adjustable and programmable output voltages from 0.8V to 19V.

The MAX1724EZK50-T unit is an easy-to-use and cost-effective PMIC with several innovative features and a wide range of applications. It is part of the powerful voltage regulator family of PMICs, specifically classified as DC-DC switching regulators. It is a space-saving, single-sided 4-by-5mm QFN-package component, offering both adjustable and programmable features.

The device\'s adjustable output voltage feature allows the user to set a voltage level between 0.8V and 19V, determined by fractional 1% increments of the resistors\' setting. Users also have the ability to program the output voltage, providing up to 5 preset output voltage levels of 0.8, 1.0, 2.5, 4.7, and 10.0V, locked with an internal OTP (one-time programmable) memory. All settings are accessible using an I2C digital interface and four external control pins.

Additionally, the component\'s innovative feature set enables a high level of system integration and efficiency. The synchronous buck topology utilizes two on-board high-side MOSFETs, each with output current monitoring and reset capabilities, which allow for total load sharing and protection. This helps users reduce board space and reduce cost without sacrificing performance.

The MAX1724EZK50-T also utilizes an advanced non-dissipative over-current protection feature. This feature keeps the MOSFETs in an OFF state while the output current remains within the regulated limits. This over-current protection feature is beneficial in high-load applications or any application that is exposed to overload conditions.

The MAX1724EZK50-T also includes a unique click-and-lock feature, which instantly saves the output voltage settings upon power cycling. This feature eliminates the need to manually reset the output voltage after a power glitch or shutdown. The component\'s wide operating temperature range of −40°C to +85°C allows the unit to be used in harsh environmental conditions.

Finally, in order to maximize power efficiency and regulate output voltage, the MAX1724EZK50-T employs state-of-the-art digital PWM control technology. This technology dynamically adjusts the on-time and off-time of the MOSFETs to maintain the desired output voltage, allowing for higher power efficiency, lower operating temperature and minimized EMI (electromagnetic interference) generation.

In conclusion, the MAX1724EZK50-T device is an ideal PMIC for applications that require high output current, adjustable/programmable output voltage, and tight voltage regulation. It offers excellent power efficiency, very low quiescent current, and minimal output ripple, making it a powerful choice for space-constrained applications.
