● Optimized for 12V/1A AC/DC adapters with <50mW
no-load power consumption at 230VAC and fast
dynamic response
● Direct drive of low-cost BJT power switch
● Adaptively controlled soft start enables fast and
smooth start-up for a wide range of capacitive loads
(from 330μF to 6,000μF) with output voltage of 12V
and above
● Very tight constant voltage and constant current
regulation over entire operating range
● PrimAccurateTM primary-side feedback eliminates
opto-isolator 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
efficiency
● Quasi-resonant operation for highest overall efficiency
● Dynamic base current control
● No external loop compensation components required
● Complies with EPA 2.0/CoC Ver5/DoE energy-efficiency
specifications with ample margin
● Built-in protections for output short-circuit, output low
impedance, and output overvoltage
● Built-in over-temperature protection (OTP)
● No audible noise over entire operating range
