The MAX1992ETG+ is an advanced integrated step-down switching regulator DC-DC controller in the PMIC – Voltage Regulators – DC DC Switching Controllers range. This device integrates all the features required by today’s power management applications and is equipped with several options to provide maximum flexibility.

The MAX1992ETG+ features excellent power conversion efficiency and high switching frequency. It provides an adjustable load transient response and operates in either burst mode operation or fixed frequency operation. It is protected against undervoltage, overvoltage and overcurrent conditions.

The MAX1992ETG+ has many application fields with a wide range of voltages. It can be used as a constant frequency DC-DC controller for notebook and desktop PC power management applications. It can also be used for power supplies for printers, LCD screens, game consoles, and other portable equipment. This device can also operate as an asynchronous boost converter for smart phones and tablets. Additionally, it can be used for solar drives, LED lighting, and automotive systems.

The MAX1992ETG+ is designed for applications that require efficiency, dynamic load performance and low noise. The feature sets have been optimized for the best possible load and transient response. This advanced device includes a slew rate control scheme which constantly monitors the state of the output voltage and dynamically adjusts the switching frequency to compensate for changing loads.

This device is equipped with a slew rate control feature which prevents large excursions of output voltage during load transients by controlling the high-side switching frequency and slew rate. Additionally, a long–term average current mode control algorithm helps to reduce high-frequency noise, often experienced in resonant topologies.

The MAX1992ETG+ features an adjustable power save mode that allows very low current consumption in light-load and no-load conditions. This device has a low-ripple Burst Mode Operation (BMO), where a fixed frequency is selected as the maximum switching frequency. This mode reduces output ripple, particularly during light-load conditions.

The MAX1992ETG+ provides a variety of protection features for safe operation. These features include undervoltage lockout, overcurrent protection, and overvoltage protection. Additionally, the MAX1992ETG+has over-temperature protection that prevents excessive heat buildup within the device. To keep track of the power controller performance, there is an Integrated Current Sense Output which can monitor the output current.

The MAX1992ETG+ is an ultra-fast, high-performance DC-DC controller that offers a wide range of features and protection functions. It is capable of delivering highly efficient power conversion solutions with minimal noise and superior transient response. With its adjustable power save mode and a host of protection features, the MAX1992ETG+ is an ideal choice for a multitude of power management applications.
