Telecom power supply
The ever increasing data consumption, coupled with new levels of virtualization and complexity of the 5G telecom infrastructure, is bringing its demanding requirements into the telecom power arena. The improvements made in telecom SMPS performance have been driven by the reduction of the on-resistance achieved in high voltage MOSFETs. To achieve the current demanding, flat energy efficiency targets, Infineon‘s medium-voltage OptiMOS™ power MOSFETs for synchronous rectification can be uses. OptiMOS™power MOSFET family, which is typically used for DC-DC brick solutions, coupled with gate driver ICs and microcontrollers efficiently powers the BBUs, RRUs, and AAUs of the macro and the small cells.
Infineon’s wide-bandgap technologies, such as CoolGaN™ 600 V (gallium-nitride-based) and CoolSiC™ 650 V (silicon carbide-based) for primary side and upcoming CoolGaN™ 100V/200V * for synchronous rectification enabling highest electrical conversion efficiency and robustness at attractive system costs. Infineon’s EiceDRIVER™ gate driver IC family perfectly matches the CoolGaN™ and CoolSiC™ products.
