The MAX14676DEWO+T is a Point-Of-Load (POL) synchronous step-down regulator ideal for powering FPGAs and processors in space-constrained systems. It helps maximize the efficiency of the power delivery system by allowing the user to control the output voltage and active current share/balance between multiple outputs. This device is designed to operate as a battery charger in various applications, including automotive and industrial.

The MAX14676DEWO+T POL synchronous step-down regulator has an input voltage range of 4.5V to 20V, and provides up to 3A of output current for each of its four independent outputs. The device is available in a tiny 14-pin DIP package and is specified from -40°C to 85°C. It has integrated overvoltage, overcurrent, and overtemperature protection, as well as tight output voltage regulation.

The MAX14676DEWO+T incorporates a patented digital regulation technology that regulates the output voltage to a very high accuracy and minimizes power dissipation. It also offers active current balance and current share among multiple outputs. The device includes an onboard EEPROM for storing user-defined settings, and uses a low I2C interface to communicate with the host processor.

The MAX14676DEWO+T POL synchronous step-down regulator is designed with an advanced, low IQ control architecture to achieve high efficiency. The device operates in either forced PWM or power save (PS) mode depending on load current. In the Forced-PWM mode, the device operates at a fixed frequency of 1.2MHz, allowing for the use of a small surface-mount sized inductor and capacitor. In Power-Saving mode, the device works at a variable frequency of approximately 25kHz - 250kHz, allowing it to reduce power dissipation at light loads.

The MAX14676DEWO+T also features a wide input current range of 0A to 3.25A to support various types of battery charger applications. In particular, it features fast charging support for Lithium-Ion (Li-Ion) and Nickel Metal Hydride (NiMH) batteries. Automotive applications benefit from the device\'s built-in trickle-charging feature, which provides a low current charging mode to prolong the life of an automotive battery by allowing it to charge slowly and steadily over a long period of time.

The MAX14676DEWO+T is also ideal for powering stationary and mobile systems in industrial applications. It is designed to enable the system to provide a variety of power consumption levels to accommodate ever-changing system conditions. It also offers a smooth transition between battery charging and system running modes. This helps avoid voltage drop during operation and provides a more stable power supply for critical system components.

The MAX14676DEWO+T is an ideal power solution for a wide range of applications in the PMIC - Battery Chargers field. It offers high performance, high efficiency, and a wide range of features to meet the needs of demanding applications. Its integrated features help reduce system development costs by simplifying power delivery design and providing a high performance power solution. With its high efficiency and fully-featured integration, the MAX14676DEWO+T is a valuable solution for any application that requires reliable and efficient power delivery.
