400 W 1/8th Brick DC-DC Converters Support PMBus

Murata has announced the introduction of its DSE Series, a fully isolated, 12 Vout, 400 W eighth brick DC-DC converter with a DOSA compliant digital interface to support the PMBus standard for communication and control. The Series, which also includes DAE and DCE products, has a droop load sharing option for paralleling up to three modules in some of the most power demanding applications. Further, the series meets the international TNV standard for Input Voltage with a 36-75 Vin range and provides 2250 VDC isolation for use in Power over Ethernet (PoE) applications.

The DSE series offers advanced power conversion technology, including a 32-bit Arm processor that controls critical conversion functions and delivers a digital interface for use in the end system application. The PMBus digital interface can be used to customize the modules’ configuration for specific functions and presents system engineers with critical telemetry information.

Multiple pin configurations are available, as the DSE provides a DOSA standard digital eighth brick pinout with sense, trim, and PMBus. The DAE provides a DOSA analog eighth brick pinout with sense and trim (no PMBus). The DCE is a DOSA analog eighth brick in the traditional 5-pin package. Target applications include telecommunications, networking, wireless, pre-amplifiers, industrial and test equipment.

1 W AC-DC Supplies Feature Ultra-Compact Packages

CUI’s Power Group today has announced the addition of two models to its PBO family of ultra-compact AC-DC power supplies. Outputting 1 W of continuous power, the open frame PBO-1 and PBO-1-B series are housed in vertical and right-angle SIP packages, respectively. The vertical PBO-1 series measures as small as 35 mm x 11 mm x 18 mm (1.38″ x 0.43″ x 0.71″), while the low profile, right-angle PBO-1-B series measures as small as 35 mm x 18 mm x 11 mm (1.38″ x 0.71″ x 0.43″), making them well-suited for industrial systems, automation equipment, security, telecommunications and smart home devices where limited board real-estate is a factor.
These high density power supplies feature wide input voltage ranges from 85 to 305 Vac or 70 VDC to 430 VDC for high voltage DC-DC applications. The PBO-1 and PBO-1-B come available with single output voltages of 5 V, 9 V, 12 V, 15 V, and 24 V DC and offer 3,000 VAC input to output isolation. Both series also offer a wide operating temperature range from -40°C to +85°C at full load as well as over current and continuous short circuit protections with auto recovery.

All models further feature class II construction, carry UL 60950-1 safety approvals, and bear the CE safety mark. The PBO-1 and PBO-1-B series are available immediately with prices starting at $4.74 per unit at 100 pieces through distribution.
