onsemi NCL30080
The NCL30080 is a PWM current mode controller targeting isolated flyback and non−isolated constant current topologies. The controller operates in a quasi−resonant mode to provide high efficiency. This removes the need for secondary side feedback circuitry, biasing and an optocoupler.| Part No. | NCL30080 |
