Dialog semiconductor's power mgmt ICs optimised for Freescale i.MX 6 processors

Dialog Semiconductor plc has announced its single-chip system power management ICs (PMICs) are being used to optimise the power requirements of tablets, infotainment systems, media hubs and other smart devices based on Freescale multicore i.MX 6 series applications processors.

Dialog says its flagship PMIC is at the heart of a power management reference board for Freescale i.MX 6Dual/Quad applications processors. Support for i.MX 6Solo/SoloLite is available via Dialog’s DA9053, which has previously featured on Freescale’s i.MX53 multimedia platform.

The NOVPEKi.MX6Q/D i.MX 6 Platform Evaluation Kit has been co-developed with Freescale i.MX 6 series ecosystem partner NovTech. By using Dialog’s configurable PMIC, the reference board delivers multiple settings for each peripheral voltage rail, programmable control for multiple power-on events and an accurate power consumption analysis framework to cut the power consumption of any i.MX 6 series application.

The Dialog device powers the i.MX 6 series system-on-chip and system peripherals - including external memories, WLAN, Bluetooth, GPS, FM receivers and modems - on a very small (< 200mm²) active PCB area with just a 1mm external component height, including all inductors, enabling the creation of thinner mobile products with longer battery life.

Dialog PMIC delivers over 14A total power capability to the Freescale i.MX 6 series system including CPU, memories and other peripherals on the reference board. In addition, the chip delivers an unprecedented degree of flexibility and configurability to precisely control the start-up sequences, output voltages and DVC ramps, claims Dialog.

With the PMIC’s wide supply range of 2.7 to 5.5V, the reference board is able to use a single cell lithium battery as well as 5V power supply.
