Information

The LYT0004 is specifically designed for low cost LED bulb replacement applications. LYT0004 devices integrate a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry into a monolithic IC.

The start-up and operating power are derived directly from the voltage on the DRAIN pin. This eliminates the need for a bias supply and associated circuitry plus allowing low-cost discrete inductors to be used. The fully integrated auto-restart circuit in the LYT0004 family safely limits output power during fault conditions such as short-circuit or open-loop, reducing component count and lower system cost. Package options for thru-hole and surface-mount suit different manufacturing requirements.

Key Features

  • High power factor meeting EU and USA requirements
  • Very low component count
  • Frequency jitter reduces EMI
  • No bias supply or transformer required
  • Continuous conduction mode Output Current (85-308 VAC) : 40 Ma at High PF
