IW1678-00規(guī)格書詳情
● Primary-side feedback eliminates opto-isolators and
simplifies design
● 64-kHz PWM switching frequency
● No-load power consumption < 100 mW at 230 Vac with
tight dynamic load transient response
● Able to meet < 30 mW no-load power consumption with
large value pre-load resistor
● Adaptive multi-mode PWM/PFM control improves efficiency
● Quasi-resonant operation for highest overall efficiency
● EZ-EMI ? design to easily meet global EMI standards
● Direct drive of low-cost BJT switch
● Dynamic base 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
● Low start-up current (8 μA typical)
● Built-in soft start
● Built-in short circuit protection and output overvoltage protection
● Built-in current sense resistor short circuit protection
● No audible noise over entire operating range
