The MAX77714 and MAX77752, says the company, are designed to enable designers of mobile systems to maximize performance per watt while increasing system efficiency for computationally intensive deep-learning systems on chip (SoCs), FPGAs, and application processors. The devices are targeted at applications ranging from augmented reality/virtual reality (AR/VR), gaming, solid-state drives (SSDs), security, and industrial internet of things (IIoT) to handheld devices such as cameras and home automation hubs.

The MAX77714 PMIC is offered as a complete, efficient power-management solution in a compact package to enable multi-core processor-based systems to operate at maximum performance with greater than 90% efficiency at 3.6VIN, 1.1VOUT. Packaged in a 70-bump, 4.1 x 3.25 x 0.7-mm WLP, it enables thinner, smaller devices and extends battery life up to 40% compared to stand-alone solutions, the company says.

Compared to discrete solutions, the MAX77714 integrates 13 regulators, including nine low-dropout linear regulators, real-time clock (RTC), backup battery charger, watchdog timer, flexible power sequencing, and eight general-purpose input/outputs (GPIOs). The MAX77714 is available for $2.75 (1000-up, FOB USA); the MAX77714EVKIT evaluation kit is available for $80.

The MAX77752 is a multi-channel, compact and integrated PMIC designed for applications with multiple power rails and hot-plugging capabilities. According to the company, it improves efficiency up to 90% at 3.6VIN, 1.8VOUT for longer battery life, and includes a flexible power sequencer (FPS) to allow hardware- or software-controlled power up.

The MAX77752 integrates three buck regulators (with high-accuracy brownout comparators), one low-dropout linear regulator, two dedicated load switch controllers, one in-rush current limiter, two external regulators to enable outputs, a voltage monitor for backup power control, and a dedicated digital output resource for logic control. The MAX77752 comes in a compact 40-pin, 5 x 5 x 0.8, 0.4-mm-pitch TQFN package and is available for $1.40 (1000-up, FOB USA); the MAX77752EVKIT evaluation kit is available for $100.
