■ Optimized for 12V/1.5A AC/DC adapters with
< 30mW no-load power consumption at 230VAC and
fast dynamic response
■ AccuSwitchTM technology − integrated 900V bipolar
junction transistor (BJT)
■ Adaptively controlled soft-start enables fast and
smooth start-up for a wide range of capacitive loads
(from 330μF to 6,000μF)
■ Very tight constant voltage and constant current
regulation over entire operating range
■ PrimAccurate™ primary-side feedback eliminates
optocoupler and simplifies design
■ EZ-EMI™ design enhances manufacturability
■ Intrinsically low common mode noise
■ Optimized 72kHz maximum PWM switching
frequency achieves best size and efficiency
■ Adaptive multi-mode PWM/PFM control improves
efficiency
■ Quasi-resonant operation for highest overall efficiency
■ Dynamic base current control
■ No external loop compensation components required
■ Built-in single-point protections against output shortcircuit,
output low impedance, and output overvoltage
■ Built-in over-temperature protection (OTP)
■ No audible noise over entire operating range
