I will design LTC3676-1 power source to NXP i.MX6 DualLite platform.
I would like to know what's the default voltage level of each LDO and Buck regulators if I don't use I2C to configure it ?
Simulation was not done on this part because of all of the digital content. LTspice did not have a good way to simulate the digital content. Please connect to local ADI team if you have a strong case to request for an LTspice model.
I am testing LTC3676-1 for i,mx6 quad.
However, each BUCK regulator generates a lot of heat and the output is not coming out properly.
I met the specs enough to meet the regulations, but I don't know why this is happening.
I am using LTC3676 in my design. Is there any sequence of how the buck regulator should be enabled.
Thanks for the reply. The voltage adjustment on LDO4 is a 1 times change at powerup because this LDO cannot be set with resistor divider unfortunately. I have a few more questions.
Question#1: If I ground the pin EN_LDO34, then after my CPU is started…
