Flexible PMIC optimises processor performance

Featured on Freescale’s i.Mx53 multimedia reference platform, the DA9063 includes support for multiple external memory configurations and combines a powerful 1.8A rated dual-input DC/USB power path router with a switching battery charger. Interfacing directly to a Li-ion/polymer battery pack, the quad buck PMIC subsystem delivers unprecedented power-up flexibility with exceptional energy efficiency to designs based around processors from Freescale, Marvell, Renesas and Samsung.

The DA9063 PMIC supports precise current/voltage charging as well as pre charge and USB modes without processor interaction. Enabling higher capacity batteries to be rapidly charged at currents up to 1.8A with minimum thermal impact to space-constrained PCBs, the die temperature is thermally regulated during charging.

The power efficiency and flexibility of the DA9063’s switching input stage is maintained to the generated supplies. Dynamic voltage scaling is permissible on up to five supply domains, allowing optimal processor energy-per-task performance. The 14 user-programmable switched/linear regulators, controlled by a programmable digital power manager, can be configured for a variety of start-up sequences, levels and timings. Supporting USB suspend mode operation, the DA9063 features USB power inputs that are internally protected against over-voltage conditions for robustness.

David Blissett, Ismosys, commented: “The DA9063’s autonomous power path controller seamlessly detects and manages energy flow between an AC adaptor, USB cable and battery whilst maintaining USB power specification compliance. The internally-generated system power rail supports power scenarios such as instant-on with a full discharged battery. A reverse-protected backup battery charger is also integrated into the power path function”.

An energy-optimised solution suitable for portable handheld, wireless and infotainment applications, the DA9063 is ideally suited for powering the latest generation of demanding portable media and wireless computing applications. Available in both consumer and automotive grades, the device is supplied in a 169 ball VFBGA 7 x 7mm package or VFBGA 11x11mm package.

Support for Freescale i.MX 6Dual/Quad applications processors

The Dialog DA9063 is at the heart of a power management reference board for Freescale i.MX 6 series Dual/Quad applications processors. Co-developed with Freescale i.MX 6 series ecosystem partner NovTech, the NOVPEK i.MX6Q/D i.MX 6 Platform Evaluation Kit enables OEMs to more rapidly bring to market precision-controlled, high-end systems based on i.MX 6 series processors.

The quad buck PMIC subsystem 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.

“The DA9063 delivers over 14A total power capability to the Freescale i.MX 6 series system including CPU, memories and other peripherals on the reference board. 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,” concluded Blissett.
