Hi,
My questions are pertaining to innoswitch 4 CZ family.
- Can innoswitch4 CZ series be used without clampZero? Can I ground the HSD pin and use CZ controller?
- How to use innoswitch 4 CZ controller without any delay between secondary request and primary switching?
- what is the range of switching freq of this family ?
- What is the blanking time for pri current sense and what is the min recommended Ton of pri FET?
- How is primary switch duty cycle calculated in PIXIs?
Hi Pranit,
thank you for considering to use PI products for your design.
I will answer all of your questions, but first I would like to ask if it is possible to use InnoSwitch4-QR instead of InnoSwitch4-CZ in your application. InnoSwitch4-CZ is optimized for use with ClampZero and will provide inferior performance without it. InnoSwitch4-QR is designed to be used without ClampZero and seems to fit your needs better.
