● No-load power consumption < 50mW at 230VAC along

with fast dynamic load response and short turn-on

delay in typical 20W and above adapter applications

● Primary-side feedback eliminates opto-isolators and

simplifies design

● 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

● Tight constant-voltage regulation across line and load

range

● Intelligent low power management achieves ultra-low

operating current (~250μA) at no-load

● Proprietary optimized 79kHz maximum PWM switching

frequency with quasi-resonant operation achieves best

size, efficiency and common mode noise

● User-configurable 5-level cable drop compensation

● EZ-EMITM design enhances manufacturability

● Adaptive multi-mode PWM/PFM control improves

efficiency

● Built-in single-point fault protections against output

short-circuit, output over-voltage and output overcurrent

● Dedicated pins for external over-temperature

protection and over-voltage protection, with latch

function available

● Tight constant current control enables output current

limit and over-load protection

● SmartDefender? smart hiccup technology

helps address issues of soft shorts in cables and

connectors by effectively reducing the average output

power at fault conditions without latch

● On-chip internal over-temperature protection

● No audible noise over entire operating range
