Dialog introduces PWM IC with higher configurability

Press release; Meiling Chen, DIGITIMES [Thursday 12 February 2009]

Dialog Semiconductor has introduced the DA9052, an advanced system power management (PWM) IC that offers designers flexibility in reducing power consumption, size and cost in handsets and other portable multimedia devices. Conceived as a platform-PWM IC, the DA9052 is capable of supporting all major families of application and mobile graphics processors.

Up to 14 power supplies, 16 GPIOs and other system function behaviour may be adapted in different operating modes as a means of eliminating power consumption overhead in the host processor. This system wakeup/mode control within the PMW IC reduces design cycle time and complexity by enabling software and application development to start at an earlier phase using a pre-validated PMW IC platform.

The DA9052 is set up through a graphical user interface in Dialog's Power Commander software utility. This configures power sequencing and multiple sleep modes. The device integrates four DC/DC buck converters and 10 programmable LDOs on-chip, and the LDOs can be connected to the DC/DC converters to improve system efficiency. Each output can be connected in series or parallel, adding further flexibility.

The DA9052 is supplied in a dual-row QFN86 (7 x 7mm) package with 0.5mm pitch. Samples are available now. Pricing is from US$3.80 each in 1000 quantities.
