Integrated Device Technology Inc. announces the IDT P95020 power management IC (PMIC). The device's unique architecture features an embedded MCU, best-in-class high-fidelity audio subsystem, clock generation, resistive touch controller, backlight LED driver, Li+/Polymer battery charger, multi-channel DC/DC converters and a high resolution ADC. It offers full programmability and flexibility into designs using leading multimedia application processors. All of the functional blocks can be accessed via I�C. The programmable regulators satisfy the dynamic voltage adjustment required by application processors.

The device targets portable consumer products, such as smart phones, portable navigation devices, mobile Internet devices and eBooks.

"The IDT P95020's innovative architecture, with an embedded CPU, can manage all on-chip resources and also offload general housekeeping and I/O processing tasks from the application processor. This unique feature, along with programmable system power regulation blocks and an on-chip power management scheme, results in higher system performance and longer battery life," said Farshad Zarghami, senior director of product marketing at IDT. "Building around the IDT digital heritage combined with leadership in high-performance silicon timing, PC audio codec excellence and integration of newly developed high-performance mixed-signal mega blocks, the IDT P95020 is the first in a series of next-generation Intelligent System Power Management solutions being developed by IDT as part of its mixed-signal SoC growth strategy."

The IDT P95020 is the latest generation of cost-effective, customizable PMICs that provide optimum performance, functionality, programmability and flexibility to the system designer of portable consumer applications. Its subsystems consist of multiple switch-mode DC/DC converters and LDO regulators, battery charge management, white LED drivers, low-power stereo audio and voice codecs with a mixer function, Class-D amplifier and headphone driver, a PLL for on-chip and off-chip clock generation, and a touch-screen controller. The embedded CPU utilizes on-board system management resources, such as instrumentation SAR 12-bit ADC and a real-time clock to provide optimum flexibility while reducing overall system power dissipation. The IDT P95020 PMIC is the first of its kind to integrate all the system power regulation and management functions along with human interface subsystems, such as audio and touch user interfaces.

To help customers design their next-generation devices using the IDT P95020, IDT provides evaluation kits, pre-defined sample scripts and the IDT GUI-based scripting tool.

The IDT P95020 is currently sampling to qualified customers and is available in a 10mm x 10mm, 132-pin QFN package and a 7mm x 7mm WCSP package. The IDT P95020 is priced at $3.72 for 10,000 units.
