Cherokee International Rolls Out Eighth Brick Intermediate Bus Converter
First-to-market DC/DC converter packs 197W per cubic inch using 40 percent less space than quarter bricks
Tustin, Calif., February 10, 2004 - Cherokee International, a leading manufacturer of power supplies, today announced its first-to-market, eighth brick isolated C-BUS converter - an intermediate bus converter (IBC) operating at 94 percent efficiencies to deliver 197W per cubic inch and 14A in a 12V output configuration. This narrow input (42 to 53Vdc) quasi-regulated converter has an output voltage range of 9.7 to 13.3Vdc. Cherokee's latest bus converter is designed specifically to overcome many of the board-level power-distribution issues of today's high-functionality silicon ICs used in optical networks, routers, servers, and storage switches. Measuring just .89 inches by 2.3 inches by .417 inches, the Cherokee International C-BUS converter (CBE1448G1) is optimum for customers who need lower currents in a quarter brick pin-out.
The CBE1448G1 converter supports two-stage, DC power conversions in 48V systems - which in turn provide power to multiple non-isolated point-of-load (POL) converters. The proprietary driver used within this smart DC transformer minimizes switching losses to maximize efficiency and output current while minimizing the component count and converter cost.
The CBE1448G1 converter meets basic insulation requirements of EN60950 and comes complete with vital industry standard features such as remote on/off, over-temperature protection, output over-current and over-voltage protection, and input under-voltage protection. Other features include 1500Vdc input to output isolation, no minimum load requirements, constant frequency operation for predictable EMI characteristics, low ripple and noise, and auto restart after fault shutdown.
Pricing and Availability
The C-BUS CBE1448G1 converter is available in both positive and negative logic modules and is priced at $34 for quantities of 1,000 units. Samples are available now through Cherokee International.
