● Ultra-low no-load power consumption with lowest

system cost (< 20mW at 230VAC in typical 20W and

above power supplies)

● Primary-side feedback eliminates opto-isolators and

simplifies design

● Intelligent low power management achieves ultra-low

operating current (~300μA) at no-load

● Adaptive load transient detection and fast response

● Adaptively controlled soft-start enables fast and smooth

start-up for a wide range of capacitive loads (from

330μF to 6,000μF) with output voltage up to 12V

● Tight constant-voltage regulation across line and load

range

● Proprietary optimized 79kHz 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

● No external loop compensation components required

● Built-in single-point fault protections against output

short-circuit, output over-voltage, output over-current,

and current-sense-resistor-short fault

● Dedicated pins for external over-temperature protection

and over-voltage protection, with latch function available

● Tight constant current control enables output current

limit and over-load protection

● No audible noise over entire operating range
