● Ultra-low no-load power consumption with lowest
system cost (< 20mW at 230VAC in typical 12V2A power
supplies)
● Fast dynamic response with secondary-side
transient detection
● 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 up to 12V
● Tight constant-voltage and constant-current regulation
across line and load range with primary-side feedback
and control
● Intelligent low power management achieves ultra-
operating current (~250μA) at no-load
● Proprietary optimized 79kHz maximum constant frequency
PWM switching with quasi-resonant operation achieves
best size, efficiency, and common mode noise
● User-configurable 5-level cable drop compensation
provides design flexibility
● EZ-EMI® design enhances manufacturability
● Adaptive multi-mode PWM/PFM control improves
efficiency
● No external loop compensation components required
● Built-in single-point fault protections against output shortcircuit,
output over-voltage, and output over-current
● Dedicated pin for user-configurable external shutdown
control
● No audible noise over entire operating range
