iW1761
iW1761 is Ultra-Low No-Load Power Digital Quasi-Resonant PWM Controller manufactured by iWatt.
Features - - Ultra-low no-load power consumption with lowest system cost (< 10m W 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 Hz maximum constant frequency PWM switching with quasi-resonant operation achieves best size, efficiency and mon mode noise - - User-configurable 5-level cable drop pensation provides design flexibility - - EZ-EMI® design enhances manufacturability - - Adaptive multi-mode PWM/PFM control improves efficiency - - No external loop pensation ponents required - - Built-in single-point fault...
