■ User-configurable output current limit

■ User-configurable light-load operation modes for

optimized dynamic load response and no-load power

consumption

■ No-load power consumption < 30mW at 230VAC with

fast dynamic load response in typical 10W compact

adapter/charger when a secondary-side controller

with Active Voltage Positioning (AVP) function is used

(iW676-30)

■ No-load power consumption < 75mW at 230VAC along

with fast dynamic load response in typical 5V, 2A

10W compact adapter/charger applications without a

secondary-side AVP controller

■ Tight constant-voltage and constant current

regulation across line and load range

■ Primary-side feedback eliminates optoisolators and

simplifies design

■ Intelligent low power management achieves ultra-low

operating current (~250μA) at no-load

■ Proprietary optimized 89kHz maximum PWM switching

frequency with quasi-resonant operation achieves best

size, efficiency and common mode noise

■ 150mV cable drop compensation

■ EZ-EMI? design enhances manufacturability

■ Adaptive multi-mode PWM/PFM control improves

efficiency

■ Complies with CoC Version 5 Tier 2 and DOE level VI

energy-efficiency specifications with ample margin

■ Built-in single-point fault protections against output

short-circuit, output over-voltage and output overcurrent

■ On-chip internal over-temperature protection

■ No audible noise over entire operating range

■ Space-saving SOT-23 package
