Complete power management on a single chip
40% power consumption compared to standard solutions
Smallest form factor for improved battery life
Maxim Integrated Korea has launched the 'MAX77714' and 'MAX77752', power management integrated circuits (PMICs) with improved battery performance and various functions, offering excellent scalability.

As high-performance application processors and SoCs are incorporated into a variety of compact devices, computational processing capabilities have increased. Users expect battery-powered devices to remain powered on and operate for extended periods without generating heat. Consequently, designers must reduce board size and component costs while simultaneously achieving high efficiency, output power, and flexible power sequencing.

The MAX77714 and MAX77752 are single-chip solutions that integrate multiple functions to reduce solution footprint and system cost. Maxim's new single-chips are applicable to a wide range of applications, including augmented reality (AR), virtual reality (VR), gaming, solid-state drives (SSDs), security, industrial IoT, cameras, and home automation hubs.

The MAX77714 provides a highly efficient power management solution in a small package. This allows multi-core processor-based systems to achieve optimal performance with over 90% operating efficiency at 3.6V input voltage and 1.1V output voltage (3.6VIN, 1.1VOUT).

The MAX77714 is available in a 4.1mm x 3.25mm x 0.7mm wafer-level package (WLP) with 70 bumps, enabling devices that are smaller and thinner than standard solutions while extending battery life by up to 40%. It integrates 13 regulators, including nine LDOs, an RTC, a backup battery charger, a watchdog timer, a flexible power sequencing (FPS), and eight general-purpose input/outputs (GPIOs), enabling shorter design cycles, lower component count, and lower bill of materials costs compared to discrete solutions.

The MAX77752 is a compact, multi-channel PMIC with multiple power rails and hot-plug capability. It delivers up to 90% efficiency at 3.6V input and 1.8V output voltages (3.6VIN, 1.8VOUT) for extended battery life and features a flexible power sequencer (FPS) for hardware- or software-controlled power operation.

The MAX77752 integrates three buck regulators with a high-accuracy brownout comparator, one LDO, two dedicated load switch controllers, one inrush current limiter, two external regulators for output, and a voltage monitor for backup power control and a dedicated digital output source for logic control. Like the MAX77714, it revolutionizes the design cycle and reduces component count and consumable costs. The MAX77752 is available in a small 40-pin, 5mm x 5mm x 0.8mm, 0.4mm pitch TQFN package.

Kevin Anderson, senior analyst for power IC research at global information provider IHS Markit, predicted that “as the importance of high-performance, highly integrated PMICs grows, the market size will grow from $291 million in 2017 to $419 million in 2021.”

“Today’s consumer application market is rapidly integrating multi-core CPUs, APUs, GPUs, neural network accelerators, and machine vision algorithms into a single, compact solution,” said Karthi Gopalan, director of business management for the Mobile Power Business Unit at Maxim Integrated. “Our latest PMICs efficiently power mobile processors to meet these evolving market demands, while delivering exceptional gaming-grade performance and scalable, configurable resources.”
