IW1709規(guī)格書詳情

● Optimized for 12V/1A AC/DC adapters with <50mW

no-load power consumption at 230VAC and fast

dynamic response

● Direct drive of low-cost BJT power switch

● 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 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

● Complies with EPA 2.0/CoC Ver5/DoE energy-efficiency

specifications with ample margin

● Built-in protections for output short-circuit, output low

impedance, and output overvoltage

● Built-in over-temperature protection (OTP)

● No audible noise over entire operating range
