IW1812-20规格书详情
● Primary-side feedback eliminates opto-isolators and
simplifies design
● Internal 800V bipolar junction transistor (BJT)
● 64kHz PWM switching frequency
● No-load power consumption < 30mW at 230VAC with
typical application circuit
● Fast dynamic load response for both one-time and
repetitive load transients
● Adaptive multi-mode PWM/PFM control improving
efficiency
● Quasi-resonant operation for highest overall
efficiency
● Ultra-low start-up current (1.7μA typical)
● EZ-EMI® design to easily meet global EMI standards
● Dynamic BJT base drive current control
● Very tight constant voltage and constant current
regulation with primary-side-only feedback
● No external compensation components required
● Complies with EPA 2.0 energy-efficiency
specifications with ample margin
● Built-in soft start
● Built-in short-circuit protection and output over-voltage
protection
● Built-in current-sense-resistor short-circuit protection
● Built-in over-temperature protection (OTP)
● No audible noise over entire operating range
