iW1819 Datasheet | Renesas

18W AccuSwitchTM Quasi-Resonant PWM Controller with Integrated 800V Power BJT 1 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 pact peak current mode PWM flyback power supplies. The device operates in quasi-resonant mode and 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...
