High-power (250-W) boost DC-DC solution for 48-V output

This knowledge item provide the Schematic,PCB layout and 3D view of High-power (250-W) boost DC-DC solution for 48-V output Industrial and Telecom applications in DesignsparkPCB format.

This high power step-up DC-DC employs a controller with a  low gate charge external MOSFET to supply 48V output for loads up to 250 W from a 24-V source.

This project provide the schematic and PCB layout in DesignSparkPCB format.

Features

• TPS40210 control IC with integrated low-side gate driver
• Low gate charge (Qg) NexFETs minimize power losses
• Fixed frequency current-mode control with internal slope compensation
• Hiccup over-current protection
• Built and tested circuit design
