Overview
iW1676 Low-Power Off-Line Digital Green-Mode PWM Controller 1.
0 Features ●● No-load power consumption < 30 mW at 230 Vac with typical application circuit (5-star rating) ●● Fast dynamic load response for both one-time and repetitive load transients ●● Very tight constant voltage and constant current regulation over entire operating range ●● Primary-side feedback eliminates opto-isolators and simplifies design ●● 64 kHz PWM switching frequency ●● Ultra-low start-up current (1.
7 μA typical) ●● EZ-EMI ® design enhances manufacturability ●● Intrinsically low common mode noise ●● Adaptive multi-mode PWM/PFM control improves efficiency ●● Quasi-resonant operation for highest overall efficiency ●●...
