TI introduces isolated DC/DC converter for low-noise 2-W power supplies

Texas Instruments Incorporated (TI) has introduced DC/DC converter for low-noise 2-W power supplies , used in programmable logic controllers, industrial automation and other noise-sensitive data acquisition designs.

The isolated DC/DC converter can be used with high-speed digital isolators, such as the ISO721 and ISO722, and isolated transceivers like the ISO1176 isolated Profibus device, the ISO35 isolated 3.3-V RS-485 device and the ISO3086 isolated 5-V RS-485 transceiver. In addition to the TPS55010, TI's popular 1-W DCP010505 open-frame power module with integrated transformer provides simple isolated power conversion and ground-loop elimination.

Key features and benefits of the TPS55010 as listed by TI:
2-W isolated power converter with integrated FETs supports variety of industrial designs. Output voltage is set by a resistor divider and the transformer turns ratio.
Wide switching frequency range (100 kHz to 2 MHz) offers design flexibility to optimize efficiency and space. Frequency can be synchronized to a master clock to reduce noise in sensitive data acquisition circuitry.
Supports -40 degrees C to +150 degrees C operating junction temperature and comes in a space-saving, thermally enhanced 3-mm x 3-mm x 1-mm monolithic QFN package.

Availability: Now.
Package: 16-pin, 3-mm x 3-mm, QFN package.
Price: $1.65 for 1K units.
