Hi,
My input voltage is 4V to 36V DC
Output voltage required is 12V, 700 mA required for other circuits. Then 12V to 5V with LDO for some circuits.
I found the IC L7986TR but it required more external components. Do you suggest any IC with very small footprint with minimal external components.
Just a thought for buck boost.. Assume there is a voltage sensing circuitry. When the voltage is lesser than 12V, the boost circuit should operate and produce the constant voltage of 12V, then the LDO to 5V. When the voltage is greater than 12V, the boost circuit to disable and only the LDO to operate. I think, in this way, it is possible to find the small footprint IC for boost circuit with one small inductor.
Thanks in advance.
