PKB4216CPIHV

New DC/DC power module series features ultra-wide output voltage range from 15V to 33V for radio frequency power amplifier applications Enhanced thermal layout improves power dissipation for cold-wall assembling Adjustable voltage range means ability to handle wide range of power transistors and reduce power consumption when system is in sleep mode New module delivers 95% typical efficiency at 30V output half load Ericsson has launched a new 200W DC/DC converter module in an eighth-brick format that has been designed for radio-frequency power amplifier (RFPA) applications and supplying the voltage to power transistors that are used in new generation of integrated radio amplifiers. Patrick Le F�vre, Marketing and Communication Director of Ericsson Power Modules, says: �In many highly integrated applications such as the latest integrated radio power amplifiers, there is limited opportunity for cooling via ventilation, therefore it becomes more necessary to employ thermal conduction via �cold wall� techniques, exchanging heat with the external environment. The new 200W PKB4216C employs advanced techniques developed by Ericsson and has been especially optimized for conduction cooling, quickly transporting heat away from system components in applications such as RFPAs.� Importantly, the new PKB4216C series module offers high flexibility with its ultra-wide adjustable output voltage from 15 to 33V, which makes it possible to power a wide range of power transistors and also reducing voltages when the RF power amplifier has been into sleep mode, thereby decreasing power consumption. Delivering power up to 200W and an output current up to 6.67A, the new PKB4216C is also ideal to power RFPA applications that use semiconductor technologies such as Laterally Diffused Metal Oxide Semiconductor (LDMOS).
