TI Introduces Miniature, I-W Isolated Dual-Output DC/DC Converter for Motor Control Applications

Nov 23, 2005

DALLAS (November 23, 2005) - Texas Instruments Incorporated (TI) (NYSE: TXN) today announced a new 1-W isolated, unregulated DC/DC converter in a miniature package. The new module operates from a 5 V input, features dual +/-7 V outputs, and is ideal for motor control, programmable logic controller and distributed I/O module applications. See www.ti.com/sc05256.

TI's DCP010507DB provides up to 85 percent efficiency and easily meets UL1950 specifications with 1 kVrms isolation and EN55022 Class B EMC performance. Supporting an operating temperature range of -40 C to 100 C, the module provides both thermal shutdown and short-circuit protection, as well as device-to-device synchronization control for applications with multiple converters. In addition, the DCP010507DB can provide highly effective point-of-load power conversion and ground loop elimination for noise-sensitive applications.
The +/-7 V output allows digital designers to incorporate a low-cost linear regulator to provide very low noise power to digital circuits and a true zero when used with op amps. This new converter can also be configured as a single-output 14 V converter.
The tiny module uses reliable semiconductor lead-frame construction and a highly integrated package design with a power density of 2.4 W/cm3. Plus, the DCP010507DB comes in Pb-free/RoHS surface-mount or through-hole package options, and in tape and reel, which can reduce manufacturing cost and time to market.

Available Today

The DCP010507DB is available now from TI and its authorized distributors in JEDEC PDIP-14 and SO-14 gull-wing packages. The products are priced from $5.90 in 1,000 piece quantities (suggested resale pricing).
