● No-load power consumption < 30mW at 230VAC along

with fast dynamic load response and short turn-on

delay in typical 5V, 2.4A 12W compact adapter/charger

applications

● Tight constant-voltage and constant current regulation

across line and load range

● Primary-side feedback eliminates opto-isolators 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-EMI? design enhances manufacturability

● Adaptive multi-mode PWM/PFM control improves

efficiency

● Complies with DoE External Power Supply and EU

CoC Version 5, Tier 2 standards

● 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

● 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
