Infineon Technologies AG (Germany) announced its CoolSET F3 third-generation, integrated, multi-chip, power IC family, which allows switch-mode power supply manufacturers to quickly design lighter, more cost-effective power supplies with high reliability and optimized efficiency. Typical applications are power supplies for DVD recorders, flat-panel LCD monitors, digital video cameras, and adapters for notebooks and other portable devices.
The CoolSET F3 products combine a power MOSFET implemented in the Infineon CoolMOS™ technology with a new multi-featured, fixed-frequency, pulse-width-modulation control IC in a single package. A maximum on-state resistance of 650 milliohms at a gate voltage of 10 V in the DIP-8 packages is about 40 percent lower than that of the closest competitor, according to the company. The CoolSET F3 products feature a broad array of built-in functions. In addition, integrated startup cells eliminate the need for an external dropping resistor and shorten the power-up time enabling lower system cost.
The CoolSET F3 family will be available in sample quantities in June 2004. In quantities of 100,000 pieces, the unit price will be below €1.50 for a 650 milliohm CoolSET in a DIP-8 package. A CoolSET F3 evaluation package will also be available.
