Emerson Network Power Introduces Latest Astec Brick 300Vin Integrated DC/DC Converter With I2C Communication

Device Features 600 Watts of Output Power with 250 to 420V Input Voltage Range

CARLSBAD, Calif. - July 6, 2005 - Emerson Network Power, a business of Emerson (NYSE:EMR), has announced its latest high-power integrated DC/DC brick converters - the full-featured Astec AIF-300Vin Series from Astec Power (astecpower.com), following the recent launch of their well-received Astec AIH 250W half-brick. With power density up to 108W/in3, the new devices can deliver up to 600 Watts of output power from an input range of 250VDC to 420VDC. The series includes six models with single-output DC voltages of 1.8V, 3.3V, 5V, 12V, 15V, 24V and 48V.

In addition to substantial advances in power density, the Astec AIF-300Vin family offers a host of embedded functions that include monitoring, protection, and adjustment capabilities as well as a communication bus that can store valuable end-user information. By including these capabilities in the converter itself, designers need not create these features externally on the circuit board. Along with streamlining design time, this flexibility frees up board space and allows for future increases the density of the design.

Operating at a wide baseplate temperature range from ?40ºC up to 100ºC, the new models reach up to 90 percent efficiency at 5V output. The key embedded functions include: current sharing, enable (positive and negative option), output voltage adjust; clock-in (for synchronization in parallel application), temperature monitoring and output current monitoring.

With increasing needs for storing and communicating significant end-user information, the devices also include the increasingly popular I2 C Interface with an internal EEPROM for data storage. To minimize external connections and optimize control, the Astec AIF-300Vin also incorporates an internal microprocessor that can control all of the monitoring and adjustment features through the I2C Interface bus. Beyond these monitoring and control functions, all models offer a number of safeguards such as overtemperature, overvoltage and overcurrent protections.

Designed with state-of-the-art components, the Astec AIF family employs surface-mount designs that simplify manufacturing while enhancing quality and reliability. As with all of Astec's DC/DC products, the new families meet international performance and safety standards including those from UL, cUL, TUV and CE.

Priced from $220 each in OEM quantities, the 1.8V, 3.3V and 5V output models are available now, while the 12V, 15V, 24V and 48V output models will be available in July 2005.
