Other Parts Discussed in Thread: TPS64203, LM5169, LM5164
Hi,
I'm in need of a synchronous (for high efficiency) DC-DC buck converter with a 120V (max) input and 3V output. Is it possible to use TPS40041 where VDD is initially generated from 120V through a resistor? The VDD is also connected from o/p via a diode, so it can draw current from o/p after start-up.
I cannot find any part for buck converter/regulator that can handle 120V input and 3V/800mA output current.
Also like to consider TPS64203, but this one is not a synchronous.
