OR:  

The SSL3401HN is a Switched Mode Power Supply (SMPS) controller IC. It operates in combination with a phase cut dimmer and a 12 V (AC or DC) low voltage electronic or magnetic transformer. It is designed to drive LED devices and include a dimmer conduction phase detector.

The chip includes a hysteretic controller for the power converter. It is most suitable for use with a linear LED current source. Two embedded Proportional-Integral (PI) controllers and a 0.052 % resolution PWM generator, adjusted by the dimmer conduction phase, ensure excellent LED current stability for a dimming range from 100 % to less than 5 %. It also minimizes the power loss across the LED current source.

Several protection mechanisms are available:

  • OverVoltage Protection (OVP)
  • Coil Current Limitation (CCL)
  • Short LED protection (SLED)
  • Open LED protection (OLED)
  • UnderVoltage LockOut (UVLO)
  • Advanced adaptive OverTemperature Protection (OTP)

Features and benefits

  • Easy migration to existing lighting control infrastructure
  • Supports most available dimmers and low-voltage transformation solutions
  • Excellent stability of LED current
  • Double PI controllers to enhance the line regulation of the LED current
  • Optimized dimming curve for low voltage transformer compatibility
  • Automatic supply frequency detection for seamless operation with 50 Hz, 60 Hz or DC sources
  • Dimmer conduction angle detection
  • Coil current limitation
  • Temperature roll-back protection
  • OverVoltage Protection (OVP)
  • Power-On-Reset (POR)
  • Shorted LED protection
  • Open LED detection

Applications

  • General LED lighting with various power requirements
  • Dimmable 12 V MR16 and AR111 applications
