Power supply for DSP solutions

TI's TPS56xx family of integrated power supply devices for high-performance DSP solutions delivers higher output drive capability and offers a higher level of integration than is available on the market. With this capability, designers of high-performance DSP applications can lower system costs and increase power supply efficiency up to 95 percent, depending on the specific application.

Advanced hysteretic control features, not typically found in comparable power supply devices, have been integrated into the TPS56xx family. These features allow the devices to monitor their output and maintain the precise level of power needed for effective system operation. With programmable hysteretic controls, the devices are able to quickly respond and compensate for load transients when system functions dictate that the power supply output must suddenly increase or decrease.

This family of power supply devices consist of the TPS5615, TPS5618, TPS5625 and TPS5633 with output voltages of 1.5 V, 1.8 V, 2.5 V and 3.3 V, respectively. With this range of voltages, designers can more easily implement mixed voltage systems. For example, a 1.8-V supply can be used for a DSP core while a 3.3-V device is used for the DSP's input/output (I/O) functions.

The TPS56xx family comes in TI's PowerPAD™ package for improved thermal characteristics. Limited samples of the devices are now available. Evaluation modules, demonstration boards and application notes also will be available.

Suggested resale pricing in U.S. dollars in 1K quantity. PowerPAD is a trademark of Texas Instruments.
