The MAX77801ETP+ is a highly-integrated, compact PMIC solution for mobile electronics applications. It is part of a family of DC-DC switching regulators, which provide an efficient, cost-effective power management solution for a variety of application fields, such as smartphones and tablets.

The MAX77801ETP+ DC-DC switching regulator features a 3A, ultra-low dropout (ULDO) high-side regulator with a switching frequency up to 2MHz. It is designed to provide high efficiency, stability, and precise output voltage, while maintaining a very efficient power solution.

The MAX77801ETP+ DC-DC switching regulator is designed to provide a precise, low output noise, and low dropout operating range to allow for maximum design flexibility. The integrated voltage references, gate driver, and gate driver P-chan FETs ensure high system reliability and performance. The DC-DC switching regulator also features power good and over-current protection and output tracking.

The MAX77801ETP+ DC-DC switching regulator design also incorporates features such as an adjustable output voltage range from 0.6V to 2.8V, an adjustable low-side (LED) driver current from 0mA to 7mA, and an ultra-fast internal soft start. The external MOSFETs are optimized for high-side saturation current and low gate charge to reduce switching losses.

The MAX77801ETP+ DC-DC switching regulator can be configured for either a constant current or constant voltage operation. It is capable of operating from input sources down to 2V, making it well suited for low voltage regulated power supply applications. Additionally, the MAX77801ETP+ is ideal for battery operated devices as well as automotive applications where power consumption and reliability are of vital importance.

The MAX77801ETP+ DC-DC switching regulator also provides enhanced system performance and protection features. The embedded thermal-shutdown feature monitors the actual temperature of the chip and limits the output current in ambient temperatures above 85C. The slew rate of the output driver current is easily adjustable via the PMIC\'s control interface, allowing the designer to optimize the output current reduction to minimize system heat production.

The MAX77801ETP+ DC-DC switching regulator is an ideal solution for a wide range of applications including mobile phones, tablets, PDAs, personal media players, and automotive audio systems. It is also well suited for industrial, consumer and medical applications where power efficiency and system protection are of paramount importance.
