Infineon Technologies AG Evaluation Boards VD_REF_XDP_48V_TO_POL

Reference design board 200 W dual output 48V-to-PoL single step converter with XDP™ digital power controller This 200 W 48 V dual digital point-of-Load is a telecom power solution with a unique setup of non-isolated SMPS and single-stage 48 V-to-PoL to eliminate the switching losses of conventional two-stage solution. This compacted and innovative power system contains a hybrid architecture of 48 V DC to 12 V DC synchronous buck and 48 V DC to 1 V DC half-bridge current-doubler solution to ensure Intermediate Bus and Direct Conversion to Point-of-Load. Dual outputs provide 200 W output power in a wide input voltage range 36 V – 75 V with an impressive efficiency of up to 97 % and voltage accuracy up to ±0.5 % over full temperature range -40 °C to 125 °C. The latest and best-in-class Infineon devices were combined with XDPP1100 XDP™ digital power controller to achieve the highest efficiency and power density. Infineon’s OptiMOS™ 5 power transistors BSC040N10NS5 / BSC070N10NS5 and BSC009NE2LS5I are best-performing low parasitic devices to achieve incomparable performance with minimum stress on the devices. OptiMOS™ FETs are driven by Infineon’s 2EDN7524G / 2EDL8112G EiceDRIVER™ gate drivers with fast short-circuit protection (DESAT). Besides that, a complete symmetrical half-bridge power solution, DHP1050N10N5, brings all its OptiMOS™ 5 benefits and minimizes board size due to its based FETs and driver integration.
