Product details

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.
