Power management ICs unveiled by Dialog Semiconductor

The DA9053 and DA9021 devices support major mobile graphics and application processor families. The DA9053 becomes Dialog's flagship system level PMIC for high end multicore based applications and supports the ARM Cortex family, while the DA9021 addresses lower power cost sensitive applications. "Dialog's latest generation PMICs extend the company's leadership in configurable system power management via multicore support," said Udo Kratz vice president and general manager of Dialog's audio and power management business unit. "Through our Processor Partner Programme we have already gained multiple design wins across a broad range of applications and expect the first DA9053 based consumer devices to be on store shelves around Q3 of this year." The DA9053 provides multiprocessor core power and delivers 'unprecedented' power up flexibility with energy efficiency. It combines a 1.8A rated dual input dc/USB power path router with a switching battery charger and includes support for multiple external memory configurations. The device is suitable for powering the latest generation of portable media and wireless computing applications, such as tablet pcs. The DA9021 delivers the same engine to optimise power up sequencing and is targeted for lower power single processor core portable consumer markets, such as e-readers and DAB receivers. It includes a 1.3A single input USB charger and its internal regulators deliver approximately half the total current relative to DA9053.
