Datasheet Summary
Low-Power Off-Line Digital Green-Mode PWM Controller
1.0 Features
2.0 Description
- - Primary-side feedback eliminates opto-isolators and simplifies design
- - Adaptively controlled soft start enables fast and smooth start-up for a wide range of capacitive loads (from 330 μF to 6,000 μF)
- - Active start-up scheme enables shortest possible turn-on delay
- - Direct drive of low-cost BJT switch
- - Very tight constant voltage regulation
- - EZ-EMI ® design enhances manufacturability
- - Intrinsically low mon mode noise
- - Optimized 72 kHz maximum PWM switching frequency achieves best size and efficiency
- - Adaptive multi-mode PWM/PFM control improves efficiency
- - Quasi-resonant...
