Description
The iW1819 integrates a high performance AC/DC power supply controller using digital control technology and a power BJT switch in one package to enable compact peak current mode PWM flyback power supplies.
Features
- multiple key protection features, allowing designs with improved efficiency and lower EMI, while lowering the bill of material cost. The iW1819 features a distinctive soft-start scheme, which allows for fast and yet smooth start-up with both small and large capacitive loads. It removes the need for a secondary feedback circuit while achieving excellent line and load regulation. It also eliminates the need for loop compensation components while maintaining stability across all operating condition.
