MAX1937EEI+T is a PMIC, Voltage Regulators, DC DC Switching Controllers device developed by Maxim Integrated. It helps control the output voltage and current of the power conversion system and helps minimize complexity in the power circuit design.
MAX1937EEI+T is a highly integrated, high voltage, step-down switching regulator controller device with integrated low side MOSFET. The device supports high current output and tight voltage regulation over the full industrial temperature range (–40 to 125°C) with high efficiency.
The MAX1937EEI+T application field includes automotive and embedded high power applications, such as 5V DC/DC converters, high-side drivers, buck converters, uninterruptible power supplies, and point-of-load (PoL) applications.
MAX1937EEI+T Working Principle
The MAX1937EEI+T operates with a fixed frequency current-mode control and amplitude modulation. The fixed frequency current-mode operation allows for fast loop settling times and tight regulation over the entire temperature range, with minimal deviation from the nominal output voltage and current. The transition between current-mode and voltage-mode techniques is achieved by modulating the frequency of the converter. The MAX1937EEI+T\'s transition between current-mode and voltage-mode techniques is also accomplished by modulating the amplitude or duty cycle of the switching frequency.
The device provides minimal complexity during the power conversion design phase by integrating a low-side MOSFET and a sophisticated, highly accurate and wide voltage range comparator circuit that acts as an error amplifier with low noise over a broad bandwidth. The low-side MOSFET can be paralleled if larger loads are necessary and an internal delay circuit provides slow start-up. This helps reduce the requirement for external components.
The device also includes many protection features such as thermal shutdown, overvoltage protection (OVP) and overcurrent protection (OCP) with programmable current limit which allows the monitoring of output current in the paralleled MOSFET condition.
The MAX1937EEI+T enables the designer to achieve efficient, robust, and low cost motor control designs without any additional external components.
In summary, MAX1937EEI+T is a highly integrated, high-voltage step-down switching regulator controller device with integrated low side MOSFET, ideal for automotive and embedded applications requiring high current output and efficient controller with tight voltage regulation of power converter.
