Infineon Offers New CoolMOS CP Series MOSFETs

Power Semiconductor developer Infineon Technologies AG (Germany) announced its new CoolMOS™ CP Series of metal-oxide semiconductor field-effect transistors (MOSFETs), which extend its portfolio of chips for high-efficiency power supplies used in telecommunications, notebook computer, and consumer appliances. Like the previous CoolMOS CS Series, the new CP Series devices feature a low on-state resistance.

The CoolMOS CP MOSFETs are intended for the power-factor correction and pulse-width modulation stages in medium-level power supply applications, such as telecommunications, notebook adapter, and consumer devices. The new products have a voltage-blocking capability of 600 V in a wide variety of package types. The low on-state resistance and low gate charge allow designers to reduce the conduction and switching losses of power supplies. For example, capacitive losses at 400 V can be reduced by 25 percent. Reduction of conduction and switching losses drives increased efficiency, and enables engineers to raise the power subsystem clock speed, leading to efficient and compact power supplies. Alternatively, power supply output can be increased without changing other aspects of the design, resulting in lower system cost per watt of rated power.

Priced between $0.70 and $1.80 in quantities of 100,000 units, in a TO220 package, the CoolMOS CP Series is available in TO-252 D-PAK, TO-220, TO-220 FP (available by the end of 2005), TO-263 (D2PAK), and TO-247 packages.
