Beschreibung

This manual describes the performance, technical data and connection of the SSL5101DB1224 20 W flyback high-power factor universal mains demo board.

The SSL5101T is a highly integrated switching mode LED controller which enables constant current driving from the mains input. It is a solution for small to medium LED retrofit lamp applications. It can be optimized for high-power factor requirements.

The SSL5101T is a flyback converter controller suitable for isolated, non-dimmable LED retrofit lamps. It can drive long LED strings with up to 40 V forward voltages (typical).

The SSL5101DB1224 demo board is intended to operate with high output voltages, as present in modern LED modules.

Eigenschaften

  • LED controller IC for driving strings of LEDs or high-voltage LEDs from rectified mains
  • High-efficiency switch mode buck, flyback or buck-boost controller driving an external power FET
  • Two maximum switching frequencies for highest efficiency or smallest application size
  • Zero current switching at switch turn-on
  • Zero voltage or valley switching at switch turn-on
  • Selectable low THD or low LED current ripple modes
  • No binning on LED forward voltage required
  • LED current accuracy within ±4 % across variations in components and conditions
  • Built-in Protections:
  • UnderVoltage LockOut (UVLO)
  • Leading-Edge Blanking (LEB)
  • OverCurrent Protection (OCP)
  • Internal OverTemperature Protection (OTP)
  • Brownout protection
  • Output short protection
  • Output open protection
  • Mains synchronization loss protection
  • Low component count LED driver solution
  • Compatible with wall switches with built-in indication light during standby(
  • IC lifetime matches or surpasses LED lamp lifetime

Typische Anwendungen

  • LED lamps with accurate current output for single or universal mains voltages
