Here is a release on the device family:
Akros Silicon, a premier supplier of leading-edge intelligent energy management ICs, today announced the new Energy$ense family of multi-output, digital DC/DC power management unit (DPMU) ICs. Energy$ense technology features include real-time power measurements and power-subsystem health monitoring, high efficiency (94% peak) and ultra-low standby current (<10uA), digital power control (via I2C) for selectable power operating modes, fast transient-handling capability for implementing adaptive power profiles, built-in spread-spectrum clocking for EMI management, and built-in sophisticated PWM-dimming for battery-draining LED-backlight displays.
“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. For detailed part number information, please see the AS19xx Product Page: (www.AkrosSilicon.com/Energy$ense_DC-DC).
The AS19xx product family is offered in 5x5mm, 32-lead RoHS-compliant QFN packages, in industrial temperature ranges from -40°C to +85°C. Products are in full production and priced starting at $1.46 per unit in 3K quantities.
