Summary:

The flyback converter using LinkSwitch-XT provides 2 W of precisely regulated constant voltage output. It also meets the requirements for load efficiency and no-load power consumption in all energy efficiency standards (CEC external power supplies).

design feature

• Constant voltage solution with low cost and low component count - 20 components
• Patented IC design and transformer winding technology enable drain nodes
• Clampless design (Clampless)
• ±5% accuracy over-temperature protection threshold - self-recovery with hysteresis - to ensure PCB board temperature is within safe limits
• Automatic restart: protection when output short circuit and loop open loop
• IC creepage distance is greater than 3.2 mm: Prevents arcing in high humidity applications
• Easily meet all external power (EPS) energy efficiency standards
• Have sufficient margin to meet CISPR-22 Class B EMI requirements
