Off-Line Digital Green-Mode Quasi-Resonant PWM Controller
1.
0 Features
●● Optimized for 5V2A AC/DC adapters/chargers with 30mW no-load power consumption at 230VAC and fast dynamic load response for both one-time and repetitive load transients
●● Direct drive of low-cost BJT power switch
●● Very tight constant voltage and constant current regulation over entire operating range
●● PrimAccurateTM primary-side feedback eliminates opto-isolators and simplifies design
●● EZ-EMI® design enhances manufacturability
●● Intrinsically low common mode noise
●● Optimized 72kHz maximum PWM switching frequency achieves best size and efficiency
●● Adaptive multi-mode PWM/PFM control improves effi...
