● 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
