"Lab power supply in chip" - Digitally Controllable Off-Line CV/CC QR Flyback
(1/1)
Miyuki:
Hi,
I just browsing new chips and found this interesting beast
InnoSwitch3-Pro Family
Digitally Controllable Off-Line CV/CC QR Flyback Switcher IC
with Integrated High-Voltage Switch, Synchronous Rectification
It have digitally controlled CV/CC/CP over I2C and cost very little
It have output 3 V to 24 V up to 100W
So nice base for small lab supply, I dont need one, but awesome what you can get today in one package
Miyuki:
Thanks for great inside info :-+
Just wonder if it is silicon based integrated switcher do they use separate logic and power device chips or do they build it on same die ?
I can agree with you about way to two transistors at higher power levels, just need that high side driver
I dont see issue with digital feedback if whole controller is digital. When they have it good implemented. Or they use some way of DAC and analog control loop ? That make no sense with today computing speeds. Complete digital controllers are much more convenient in this way.

Nice chip. Just for now I looked at their design tool and managed to get an optimized 10W DC-DC supply with input voltage of 36-42V. Not risking to build a real mains AC-DC.
