@copilot Would this work as an ltc3779? I need the output to be 12v

3mo

The LTC3779 and LTC4007 serve different purposes. The LTC4007 is a lithium-ion battery charger IC, while the LTC3779 is a high-efficiency, 4-switch buck-boost DC/DC controller. It seems that you want to achieve a 12V output, which is more aligned with what the LTC3779 can provide.

If you're looking to redesign this circuit using an LTC3779 to achieve a 12V output, here are some considerations and steps you might take:

Power Path: The connections will differ since the LTC3779 has different pin functionalities. You would need to connect the input voltage to its VIN and VOUT to where you need the 12V.

Buck-Boost Configuration: Ensure that the inductor $L1$ and other passive components are selected to handle the currents and power levels you're targeting. The inductor value may need adjustment from 10µH.

Feedback Network: Design the feedback network to set the desired output voltage. The resistors in your current design might need changing to set the output to 12V accurately.

High-Frequency Operation: Ensure the appropriate compensation network if you plan to run the LTC3779 at high frequency.

Protection Features: The buck-boost converter also requires appropriate layout and component selection for stability and protection, similar to your existing design.

Additional Components: You may need additional MOSFETs or diodes, which are essential for the buck-boost topology in the LTC3779.

Unfortunately, simply replacing the LTC4007 with an LTC3779 wouldn't work without considerable modification since it involves different circuit designs and requirements. If you can provide more details on your input voltage and current requirements, we can explore further how to achieve your goal with the LTC3779.
