IW1818開發(fā)板套件編程器的評估板-DC/DC與AC/DC（離線）SMPS規(guī)格書PDF中文資料

● Targeted at 10W to 12W AC/DC applications with

<50mW no-load power consumption at 230VAC and

fast dynamic response

● AccuSwitchTM technology with 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) with output voltage of 5V to

12V and above

● Very tight constant voltage and constant current

regulation over entire operating range

● PrimAccurateTM primary-side feedback eliminates

opto-isolator 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
