Description
* Primary-side feedback eliminates opto-isolators and simplifies design * Adaptively controlled soft start-up enables fast and smooth start-up for a wide range of capacitive loads (from 330 μF to 6000 μF) * Very tight constant voltage regulation * EZ-EMI ® design enhances manufacturability * Intrinsically low common mode noise * Optimized 72 kHz maximum PWM switching frequency achieves best size and efficiency * Adaptive multi-mode PWM/PFM control improves efficiency * Quasi-resonant operation for highest overall efficiency * Direct drive of low-cost BJT switch * Dynamic base current control * No external compensation components required * Complies with EPA 2.0 energy-efficiency specifications with ample margin * Built-in short circuit protection and output overvoltage protection The iW1706 is a high performance AC/DC power sup.
