● PrimAccurateTM primary-side feedback eliminates
opto-isolators and simplifies design
● Internal 800-V bipolar junction transistor (BJT)
● Adaptively controlled soft start-up enables fast and
smooth start-up for a wide range of output voltage (5V,
12V and above) and capacitve loads up to 6,000μF
● 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 improves
efficiency
● Quasi-resonant operation for highest overall efficiency
● EZ-EMI® design easily meets global EMI standards
● Very tight constant voltage and constant current
regulation with primary-side-only feedback
● No external compensation components required
● Built-in single-point fault protections against output
short circuit, output over-voltage, and current-senseresistor
short-circuit faults
● Built-in over-temperature protection (OTP)
● No audible noise over entire operating range
