Hi,
Can we have some more data for L9758? Datasheet provides very less information. 
- Typical application schematic (external components values/part numbers)
 - Typical performance characteristics
 - Start-up, efficiency, shutdown, load and line transients waveform plots
 - Parameters' variation w.r.t Temperature
 - Type of current-mode control in switching regulators.
 
Thanks
Flexon
