Texas Instruments DC-DC Converter

An evaluation module from Texas Instruments which demonstrates an offline high-voltage buck-type converter that provides 13 Vdc output at up to 100 mA from an input voltage of 85 to 265Vac. The module uses the UCC28880 low quiescent current switching device which integrates a 700V output MOSFET and controller into one SOIC7 package and allows start-up and operation directly from the rectified mains supply. The module design features low standby power and a minimum number of external components.

• High efficiency non-isolated high-side buck converter
• Standby power < 30mW
• Pre-set output of 13V (Can be modified to 5V by installing jumper J1)
• Load range 0 to 100mA
• Universal off-line input voltage range of 85 to 265Vac
• Meets EN55022 Class B conducted emissions requirements
• Overload and output short-circuit protection and thermal shut-down
• Controlled start-up and restart after fault protection
