Dialog Semiconductor has launched a evaluation board for its DA9034 IC that enables designers to configure designs based on Marvell PXA3xx application processors. The board provides a audio and power management solution for PXA3xx-based products and is driven using a standard Windows-based graphical user interface (GUI) via a PC's USB interface. 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 low build height of less, than 1.2mm, and minimum PCB area.
The 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 lithium ion battery charging, touch screen interface, LED driving, together with voice and HiFi audio codecs. Dialog to support Dynamic Voltage Management for both switching and linear regulators. This technique along with Smart Mirror linear regulators and its 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.
