PMICs Power Next-Gen Consumer Apps

(Maxim Integrated Products)

Maxim Integrated Products’ MAX77714 and MAX77752 power-management ICs (PMICs) maximize performance per watt while increasing system efficiency for computationally intensive deep-learning SoCs, FPGAs, and application processors. They address a broad spectrum of 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


MAX77714: High-Performance PMIC for Computationally Intensive Applications


The MAX77714 PMIC delivers 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 percent efficiency at 3.6VIN, 1.1V OUT. With a 70-bump, 4.1 mm x 3.25 mm x 0.7 mm WLP package, it enables thinner, smaller devices and extends battery life up to 40 percent compared to stand-alone solutions. It reduces design cycle time, component count, and bill of material (BOM) costs compared to discrete solutions by integrating 13 regulators, including 9 low-dropout linear regulators, real-time clock (RTC), backup battery charger, watchdog timer, flexible power sequencing and 8 general-purpose input/outputs (GPIOs).


MAX77752: High-Performance, Compact, Multi-Channel PMIC with Hot-Plugging Capabilities


The MAX77752 is a multi-channel, compact and integrated PMIC designed for applications with multiple power rails and hot-plugging capabilities. It improves efficiency up to 90 percent at 3.6VIN, 1.8VOUT for longer battery life and includes a flexible power sequencer (FPS) to allow hardware- or software-controlled power up. It reduces design cycle time, component count and BOM costs by integrating 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, voltage monitor for backup power control and a dedicated digital output resource for logic control. The MAX77752 comes in a compact 40-pin, 5 mm x 5 mm x 0.8 mm, 0.4 mm-pitch TQFN package.


The MAX77714 is available for $2.75 each/1,000 and the MAX77752 is available for $1.40 each/1,000. The MAX77714EVKIT# evaluation kit is available for $80 and the the MAX77752EVKIT# evaluation kit is available for $100. For more details, refer to the MAX77714 and MAX77752 datasheets.
