Fault Protected 230 VAC In/17W Output LED Driver Using No Magnetic Components Reference Design


Design files


This 230VAC LED driver design (PMP6021) is form-factor optimized for use in recessed can fixtures, or downlights, and is dimmable using standard TRIAC wall dimmers or via analog signal from an optional MCU.  It achieves low LED current ripple and >0.9 power factor without using inductors or transformers.

  • TRIAC and analog dimmable
  • Power factor > 0.9
  • Protection Features: LED Open, Linear MOSFET Over-Voltage, Thermal Foldback
  • <25% LED current ripple results in high LED utilization
  • Low Conducted EMI, no Radiated EMI
  • 87% Efficiency at 230VAC

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
