| "Lab power supply in chip" - Digitally Controllable Off-Line CV/CC QR Flyback |
| (1/1) |

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 |

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. |
