IW1819-01数据手册规格书PDF详情

■ Optimized for 12V/1.5A AC/DC adapters with

< 30mW no-load power consumption at 230VAC and

fast dynamic response

■ AccuSwitch™ technology − integrated 800V 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
