Description

Two-stage topologies are growing in popularity because of the convenient scalability of power on the primary side as well as the features on the secondary side. High light quality, very low dimming levels, and more complex systems with sensors and MCUs require a stable output voltage enabled by constant voltage (CV) secondary-side regulated (SSR) topology. More stringent standards for flicker and total harmonic distortion (THD) as well as harmonics are also points in favor of SSR topology. The controller used in SSR configuration is suitable for on/off LED drivers and is the best solution for minimum dimming levels down to 0.1 percent and dim-to-off.

Features

  • Optimized as secondary-side-regulated (SSR) constant voltage (CV) output flyback controller, also well suited for PSR
  • Power factor (PF) > 0.9 and THD < 10% across a wide load range (AC input up to 277Vrms)
  • Integrated burst mode enables a very low stand-by power < 100mW
  • Built-in jitter function eases EMI certification without additional circuitry
  • Critical conduction mode and quasi-resonant mode with smart valley hopping
  • External start-up circuit control signal
  • Comprehensive set of protections (OVP, OCP, etc.)

Typical applications

  • LED lighting, Smart Lighting, Emergency Lighting.
  • monitor up to 125W.
  • Adapter & charger, LED driver and luminaires up to 125W
  • flat TV,all-in-one PC
