● 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
