Akros Introduces New Energy$ense Family of Multi-Rail DC/DC DPMUs

New AS19xx high-efficiency Energy$enseTM digital PMUs with multi-rail DC/DC offer 94% peak efficiency and real-time power sensing and control for total energy management



“Akros has developed the AS19xx Series of Energy$ense DC/DC DPMUs to address the growing need for a total energy management paradigm in modern platforms,” said Parviz Ghaffaripour, President & CEO. “True to our leadership in network-based energy management, the AS19xx series incorporates unique Energy$ense features on top of essential digital power manager features so that our customers can deliver power-management innovation and performance in their equipment in an efficient and cost-effective manner. Additionally, the AS19xx family of products addresses the needs of system designers by offering 10 pin-compatible products that pack a variety of features, including a wide input voltage range of 3-27V, load range of 0.5A-10A, switching frequency from 100kHz-2MHz, and internal spread-spectrum clocking with external synchronization input. These features minimize external BOM and board space, while offering great flexibility in multi-platform designs.”

The 10 devices in the new AS19xx Series come in different combinations of synchronous buck, boost and LED-drive converter configurations. With unique feature sets to facilitate simple implementation of real-time and adaptive energy management schemas, the AS19xx series is a cost-effective choice for a wide range of applications including 4G LTE residential gateways and femtocells, tablets and large display-oriented consumer devices, ultra-books, e-books, digital photo frames, NAS and media hubs, Internet-TV and IPTV set-top boxes, automotive infotainment systems, solid-state lighting, communication equipment with cluster-power or intermediate bus architectures, and many others.



The AS19xx Series consists of 10 triple- and dual-output power-managers that come in combinations of two synchronous buck regulators and a choice of a buck-boost or LED-boost controller. Devices come in either hardware-only mode or hardware and software (I2C) mode configuration. The software-mode devices provide access to advance power management features such as input power measurements, software-driven LED-dimming and daisy chaining.
