First-to-Market DC/DC Converter Packs 197W/in³ Using 40% Less Space Than Quarter Bricks
Cherokee International, a leading manufacturer of power supplies, announces its first-to-market eighth brick isolated C-BUS converter - an intermediate bus converter (IBC) operating at 94% efficiencies to deliver 197W/in³ and 14A in a 12V output configuration. This narrow input (42VDC to 53VDC) quasi-regulated converter has an output voltage range of 9.7VDC 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 22,6mm x 58,4mm x 10,592mm / (0.89in x 2.3in x 0.417in), the Cherokee 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 minimises switching losses to maximise efficiency and output current while minimising 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 1,500VDC 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.
