UC2843AQ: UC2843AQ startup optimization

Part Number: UC2843AQ

Dear team,

please support on following:

tested UC2843AQ and preparing the schematics with "startup Circuite".
We have following question:

How to implement a faster start up time but keep power dissipation LOW on Rstart? Especially at high voltage (110V)
We have the idea to use voltage stabilisation(insteat Rstart) with one NPN transistor which wil be active only at start up.


Maybe you have some additional ideas?

Thanks
