■ Ultra-low no-load power consumption with lowest

system costs (< 10mW at 230VAC in typical 5V/2A

power supplies)

■ Fast dynamic response with secondary-side load

transient detection without optocoupler

■ Built-in fast start-up

■ Direct drive of low-cost BJT power switch achieving

high efficiency

■ Tight constant-voltage and constant-current

regulation across line and load range with

primary-side feedback and control

■ Intelligent low power management achieves ultra-low

operating current at no-load

■ Proprietary optimized line/load adaptive maximum

constant frequency PWM switching with

quasi-resonant operation achieves best size,

efficiency, and common mode noise

■ User-configurable 4-level cable drop compensation

provides design flexibility

■ EZ-EMI TM design enhances manufacturability

■ Adaptive multi-mode PWM/PFM control improves

efficiency

■ No external loop compensation components required

■ Built-in single-point fault protections against output

short-circuit, output over-voltage, and output

over-current

■ On-chip internal over-temperature protection

■ No audible noise over entire operating range

■ 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
