Dead Time ,Rise and fall time of LTC3311

Hi Shreeraam, 

Please use LTppowerCAD for LTC3311 power loss estimation. 

For rise time, fall time and dead time, it depends on your operating condition. What is your VIN, VOUT and ILOAD ? 

Thanks,

Wenwei. 

Hi Wenwie,

I have provided inputs for your above  questions:

Our application operating condition:

Vin =5.051V ; Vout = 1.05V and             ILoad Max=12.292 A

Tr = ?

TF =?

Dead time=?

Line regulation%?

Load regulation%?

Hi Jhun,

LTC3311:

Our application operating condition:

Vin =5.051V ; Vout = 1.05V and   ILoad =12.292 A

Min Gain and Phase Margin? 

Rise time= ?

Fall time =?

Dead time=?

Line regulation%?

Load regulation%?

Tr = 1.5ns

TF =1ns

Dead time (low_to_high)= 1ns

Dead time (high_to_low)= 2ns

Line/Load regulation can be found in the datasheet. Please see below. 

For gain and phase margin estimation, please use LTpowerPlay, using the external components you choose with your application. 

Thanks,

Wenwei.
