Part Number: UCC27222 Other Parts Discussed in Thread: UCC27223 , , TPS28226 , LM5104 , LM27222 Hi all,
I'm looking for a half-bridge gate driver to use in a synchronous boost DC-DC design, and I'm attracted to the idea of an adaptive driver to maximize efficiency…
Other Parts Discussed in Thread: TPS51604 , UCC27222 Do you have a half-bridge driver with the facility to disable the lower FET automatically if its drain voltage is above zero, so that it can make a Synchronous buck go into discontinuous mode at low current…
Hello Kanemaru,
TI does not have a high side only driver at this time, but many half bridge drivers can be operated as high side only. I have a couple of concerns on the UCC27222 however. This part is indicated as not for new designs, so I would recommend…
Hi Hirotaka,
Thanks for asking about LM5106. I am an apps engineer and will help you out.
Figure 19 shows that the deadtime can be adjusted from 100ns to 800ns with a resistor value from 10k to 150k. A resistor value of 5k on RDT can be used however since…
Other Parts Discussed in Thread: UCC27222 , TPS2834 I am trying to look for a sync buck MOSFET driver that has adative dead time control. I like to see the low side MOSFET turned on by seeing switching node falls below certain threshold, for example 0.5V…
