Part Number: LMR14006
kindly let us know the working capability of buck converter IC LMR16004 when ramp down and ramp up voltage is applied continuously to IC.
This ripple voltage will be controlled by externally components. Ripple timing is based on the load consumption and AC input voltage.
Ramp up voltage (25V to 35V) and ramp-down voltage (35V to 25V) is applied to buck input.
The input voltage change acts as line transient to the LMR14006. The output voltage will have overshoot and undershoot, with value depending on the output cap, output voltage and output current. IC will not damage under this circumstance.
Thanks & Best Regards

What's output voltage and switching freq? Pls also pay attention on the duty cycle to make sure high side ON time >150ns.
In reply to Andy Chen:
The o/p is 3.6V and Fq is fixed in the device 1.1Mhz
In reply to Akshat Garg:
For 36V to 3.6V at 1.1MHz, estimated ON time is 104ns which is close to 95ns Ton-min, there maybe pulse skip in corner conditions.
