■ 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 5V, 2A

10W compact adapter/charger when a secondaryside

controller with Active Voltage Positioning (AVP)

function is used (iW676-30C)

■ 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

■ User-configurable 5-level cable drop compensation

provides design flexibility

■ EZ-EMITM 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

■ Dedicated pins for external over-voltage protection,

with latch function available

■ SmartDefender? smart hiccup technology helps

to address issues of soft shorts in cables and

connectors by effectively reducing the average output

power at fault conditions without latch

■ Optional on-chip internal over-temperature protection

■ No audible noise over entire operating range

■ Space-saving SOT-23 package
