Dialog Semi's DA9034-EVB evaluation board

Dialog Semiconductor Plc has launched an evaluation board for its DA9034 IC that enables designers to quickly configure designs based on Marvell PXA3xx application processors. The DA9034-EVB offers a complete audio and power management solution for Marvell PXA3xx-based products and is driven using a standard Windows-based GUI via a PC's USB interface, allowing engineers to significantly shorten development time.

With the DA9034-EVB, developers can evaluate the technical performance of the DA9034 highly integrated audio and power management IC. The DA9034-EVB can also be used in conjunction with a PXA3xx processor system to develop power management and audio control routines and verify complete designs.

The board provides a reference PCB layout and uses components typically found in cellular handset, portable media player and PDA designs, which are optimized for build height of less than 1.2mm and minimum PCB area.

Dialog's DA9034 IC integrates more than 50 mixed signal functions on a single chip, providing regulated supplies for the PXA3xx processor, memory and peripheral devices, as well as supporting Li-ion battery charging, touch screen interface, LED driving, together with voice and Hi-Fi audio codecs.

With the DA9034, Dialog said it is the first company to support Dynamic Voltage Management for both switching and linear regulators. This technique, along with the company's ultra-efficient Smart Mirror linear regulators and its flexible implementation of the dedicated PXA3xx processor Power I2C (PI2C), improves the battery life of end products. All power supplies and control signals are accessible on terminal posts and the DA9034-EVB can be used to power a complete PXA3xx platform design during development.

"As many advanced systems today require sophisticated power management, the interaction between PMICs, processors and other peripherals are key to achieving long battery life," said Ajay Parmar, Dialog Semiconductor's director of applications. "Dialog's DA9034-EVB provides an effective method of developing and testing power management software in a real system environment. In portable and cellular applications, where space is always at a premium, the DA9034/PXA3xx combination allows manufacturers to develop products in the thinnest, smallest and lightest formats."
