Dialog Semiconductor unveils multiphase DC-to-DC buck converter
Feb 26, 2013 (Datamonitor via COMTEX) --
Dialog Semiconductor plc, a provider of highly integrated power management, audio and short range wireless technologies, has announced its new programmable multiphase DC-to-DC buck converter, the DA9210, that can be scaled for use across multiple, high-end smartphone and tablet platforms to help accelerate development cycles.
The new four-phase DA9210 buck converter delivers an output current of up to 12 Amp. This can be doubled to 24 Amps when two DA9210 converters are used in parallel and up to 38 Amps when combined with the Dialog's DA9063 System PMIC to supply other power rails in the system. This makes the DA9210 ideally suited to high performance, ARM Dual big- Little or Cortex A15 multicore application processors that enable consumers to multi-task using several applications simultaneously, the company said.
By using this four-phase architecture, combined with a fast switching frequency, the DA9210 enables the use of very low profile components with a maximum height of just 1 mm to support the design of ultra-thin devices. The Dialog power management system, consisting of up to three Integrated Circuits, behaves as one, simplifying the start-up configuration and control of the power management system. Software loading on the host processor is optimized, improving customer time-to-market while minimizing the design effort of the power scheme for subsequent designs, the company added.
Udo Kratz, senior vice president and General Manager of Dialog's Mobile Systems business unit, commented, "Dialog has created the new concept of a scalable power solution with our DA9210 quad-phase buck converter. It helps to minimize the effort involved in developing subsequent designs of feature-packed, next generation smartphones and tablets to help vendors keep pace with the need to launch new models every six to nine months in response to consumer demand and competitor activity."
