Power management & signal chain companion chips for TI's OMAP35x

Texas Instruments launched three fully integrated power management and signal chain companion chips, TPS65920, TPS65930 and TPS65950. These chips support all system power requirements of an OMAP35x processor-based design to provide optimized power and performance, targeting embedded processor designs.
TI's single-output TPS6235x family of 3-MHz DC/DC converters and its multi-output TPS65023 converter, are already in volume production. Both provide flexibility in system optimization for OMAP35x designers.

The TPS659xx, TPS65023 and TPS6235x devices use a dedicated I2C communication interface.

The TPS65950 has the following features:

1. Supports up to 14-channels of power management conversion.
2. Integrated 3-MHz DC/DC converters and low-noise LDOs,
3. In-built dual audio codec and drivers, monitor and control features,
4. In-built battery charger,
5. In-built LED driver,
6. In-built 10-bit, 3-input ADC,
7. vibra and keypad functionality,
8. In-built high-speed USB transceiver with integrated 5-V power supply

The TPS65920 and TPS65930 devices offer a subset of features of the TPS65950

About OMAP: Introduced in Feb-08, the OMAP35x generation of devices consists of four distinct single-chip processors: OMAP3503, OMAP3515, OMAP2525 and OMAP3530. Based on the ARM Cortex-A8 processor, the OMAP35x processors feature combinations of a 2D/3D graphics engine, video accelerators and TMS320C64x DSP core to provide combination of integrated multi-core processing capabilities in a single chip.

Availability: The TPS65920, TPS65930 and TPS65950 are currently sampling with
volume production planned for Q4 2008.
The TPS65023 and TPS6235x devices are available in volume production.

Packaging & size: 7 mm x 7 mm BGA package (TPS65950)
10 mm x 10 mm BGA package (TPS65920 and TPS65930)

Pricing (in 1,000-piece quantities): TPS65920 is $6.10
TPS65930 is $8.25
TPS65950 is $12.40
TPS65023 is $3.30
