■ 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
