TI Presents Miniature DCP010507DB DC-DC Converter

Texas Instruments Inc. (TI, Houston, TX) presented 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 suitable for motor control, programmable logic controller, and distributed I/O module applications. The DCP010507DB provides up to 85 percent efficiency and 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 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 lead-free/RoHS surface-mount or through-hole package options, and in tape and reel, which can reduce manufacturing cost and time to market.

The DCP010507DB is available now in JEDEC PDIP-14 and SO-14 gull-wing packages. The products are priced from $5.90 in 1,000-piece quantities.
