Description

The iW1700 is a high performance AC/DC power supply controller which uses digital control technology to build peak current mode PWM flyback power supplies. The device together with an external active device (depletion mode NFET or NPN BJT) provides a fast start-up meanwhile achieving ultra-low no-load power consumption.

Key Features

  • Zero power consumption at no-load with lowest system cost (< 5 mW at 230 VAC with typical application circuit)
  • Intelligent low power management achieves ultra-low operating current at no-load
  • Adaptive load transient detection and fast response
  • Very tight constant voltage and constant current regulation over entire operating range
  • PrimAccurateTM primary-side feedback
