Texas Instruments has introduced a 1-W, unregulated DC/DC converter in a miniature package that features 3-kV isolation. The new DCH01 family of plug-in power modules operates from a 5-V input and provides single voltages of 5 V, 12 V, and 15 V and complementary dual-output voltages of ±5 V, ±12
V and ±15 V. The tiny modules are ideal for industrial applications such as data acquisition, motor control, programmable logic control, test and measurement, medical instrumentation and professional audio.

TI's DCH01 series provides up to 85-percent efficiency and easily meets UL60950 specifications with 3 kVrms isolation and EN55022 Class B EMC performance. Supporting an operating temperature range of -40° C to 85°C, the modules easily power TI's new ISO721 and ISO721M high-speed digital isolators, which were introduced in January In addition, the DCH01 provides highly effective point-of-load power conversion and ground loop elimination for noise-sensitive applications.

The DCH01 uses reliable PC-board construction, and is housed in an industry standard 20 mm x 8 mm x 10 mm SIP-7 package that is Pb-free/RoHS compliant. DCH01's open-frame design enhances reliability
by eliminating potting commonly found in competitive products.
