Additional preview pages of the iW1761 datasheet.

Ultra-low no-load power consumption with lowest system cost (< 10mW at 230VAC in typical 5V/2A,10W power supplies).
Primary-side feedback eliminates opto-isolators and simplifies design.
Intelligent low power management achieves ultra-low operating current (~300μA) at no-load.
Adaptive load transient detection and fast response.
Tight constant-voltage and constant-current regulation across line and load range.
Proprietary optimized 89k.
