Akros Silicon has announced the Energy$ense family of multi-output, digital DPMUs (DC/DC power management unit) ICs. They provide real-time power measurements and power-subsystem health monitoring, 94% efficiency and standby current of less than 10μA and digital power control via I2C for selectable power operating modes. Features include fast transient handling for implementing adaptive power profiles, and built-in spread spectrum clocking for EMI management. The 10 ICs in the series are available in different combinations of synchronous buck, boost and LED drive converter configurations. The ICs are suitable for applications including 4G LTE residential gateways and femtocells, tablets and large display-oriented consumer devices, ultra-books, e-books, digital photo frames, NAS (network-attached storage) and media hubs, and Internet-TV, IPTV set-top boxes, automotive infotainment systems, solid-state lighting, intermediate bus architectures. The ICs are available 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. They are offered in 5x5mm, 32-lead RoHS-compliant QFN packages and operate in the industrial temperature range of -40 to 85°C.
