● No-load power consumption < 20mW at 230 VAC with

typical application circuit (5 star rating)

● Fast dynamic load response for both one-time and

repetitive load transients

● Very tight constant voltage and constant current

regulation over entire operating range

● PrimAccurateTM primary-side feedback eliminates

opto-isolators and simplifies design

● Low EMI design enhances manufacturability

● Intrinsically low common mode noise

● Optimized 72kHz maximum PWM switching frequency

achieves best size and efficiency

● Active start-up scheme enables fastest possible startup

● Adaptive multi-mode PWM/PFM control improves

efficiency

● Quasi-resonant operation for highest overall efficiency

● Direct drive of low-cost BJT switch

● Dynamic base current control

● No external loop 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 overvoltage

protection

● Built-in current sense resistor short circuit protection

● No audible noise over entire operating range
