  • 1 mW power consumption at 230 V (AC)
  • Integrated 500 V clamp; no metal oxide varistor required to protect the IC
  • Self supplied, no external bias required
  • Discharge current internally limited
  • Adjustable discharge delay
  • Very high differential surge: 6 kV with two 200 kΩ resistors
  • Easier application design, resolving EMI issues while retaining the efficiency level

Target Applications

  • All AC connected power supplies with X capacitors > 100 nF requiring a low load standby power
