Converter Suited For Memory Applications

A new open-frame, quarter brick converter is capable of delivering up to 40A at voltages of 1 Vdc. Designed to meet the low voltages demanded by modern high-speed logic and memory devices, the SLC100 is suited for high-density, distributed power architectures in telecommunications, industrial, and data communication systems. Two SLC100 devices in the series, the 1.2 Vout and 1.5 Vout models, can accommodate an input-voltage range of 36 to 75 Vdc, and are capable of operating at temperatures up to 85°C without a heatsink. No minimum load is required. The devices feature an isolation voltage rating of 2,000 Vdc. Output trimming and remote output sense functions are provided, while a remote on/off capability allows the devices to be turned on and off using either negative or positive logic signals. Thermal shutdown and protection against output over-voltage and over-current conditions are standard. The converter operates with a fixed switching frequency of 400 kHz, and is designed to meet CISPR22/EN55022/FCC15J Class B specifications for EMI levels with external filtering. Efficiency levels are as high as 91%, while typical ripple and noise on the output is specified as 75 mV. Operating temperature ranges from –25°C to +85°C. The SLC100 comes in both through-hole and surface mount versions, with pricing set at less than $60 each in OEM quantities. C&D TECHNOLOGIES INC., Tucson, AZ. (800) 547-2537.
