A new power management product family consists of four sub-PMICs that offer best-in-class transient response and in-circuit digital programmability, in a smaller form factor than current market solutions.
The new product family of buck converters, which consists of the DA9217, DA9220, DA9121 and the DA9122, represents Dialog’s first sub-PMIC family with a 4-MHz switching frequency that reduces inductor size and height to allow use of smaller external components. The devices are candidates for ARM Cortex-based multi-core application processors and high-performance SoCs, FPGAs and GPUs, which enable developers to fit a 6 to 10-A power solution into limited board areas of next-generation devices spanning smartphones, tablets, notebooks PCs, DSLR cameras, solid state drives and more.
The devices drive higher efficiency without sacrificing functionality, simplifying complex system sequencing with digital programmability and configurability, for a seamless interface to the system microcontroller depending on the system requirements. The devices can support a single output up to 6 A/ 10 A or dual outputs up to 3 A/5 A per output, making them suitable for the latest 7-nm-based SoCs.
Leveraging Dialog’s power conversion prowess, the devices were optimized for users requiring high current with maximum efficiency. The sub-PMICs can run from a single cell Li-ion battery, 3.3-V or 5-V power supplies. The I2C interface enables dynamic voltage control to optimize power savings and performance, while the fault protection features also provide overvoltage, overcurrent and thermal shutdown protection.
“Designers continue to face new challenges with each passing year when it comes to power consumption and system size but are often forced to trade one feature for another,” said Scott Brown, VP Marketing of Dialog’s Advanced Mixed-Signal Business Group. “These new devices are addressing these challenges head on which continue to demonstrate Dialog’s leadership within configurable power management solutions.”
