■ 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
