Can I add a FET in parallel to this boost circuit

WebMay 16, 2024 · We designed POls with sync rect FETs on chip so that they would operate 2-phase and I saw few-% current match at low, sub-% match at high current (to ... No, you don't need to synch the converters - we used an LLC variant - parallel btw, 300A is a lot for LLC - the ripple current in the o/p caps for each stage will be ~ 120A - so you will need ... WebThis generates substantial heat requiring proper thermal management in the form of heat sinks. FETs also are not typically designed for 100s of amps on their own, so a typical FET-based design will require many FETs in parallel to handle the power (in some cases I've seen 6-10 on a single board).
