Please give your suggestions for the following power supply design.
AC to DC converter
Input voltage = 60 to 150 V AC
Output voltage = 3.3 V DC (+/-3%), 30 mA
Charge up time = 1ms from zero crossing of ½ cycle used for charging
We don’t need any isolation for the output voltage from the input side for our application.
Thanks and regards,
