Digital PMUs with multi-rail DC/DC offers 94 percent peak efficiency and real-time power sensing and control

June 29, 2011 | Paul Buckley | 222902937
Akros Silicon Inc., has unveiled the company’s 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 (<10 uA), digital power control (via I˛C) 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.

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 3-27 V, load range of 0.5 A-10 A, switching frequency from 100 kHz-2 MHz, and internal spread-spectrum clocking with external synchronization input. The features minimize external BOM and board space, while offering great flexibility in multi-platform designs.

The AS19xx Series is available 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 product family is offered in 5x5 mm, 32-lead RoHS-compliant QFN packages, in industrial temperature ranges from -40 to +85°C. Products are in full production and priced starting at $1.46 per unit in 3K quantities.
