How to make a jumppad for Character Controller?

I'm currently using deltaTime, and it's not working. I've been searching around on the internet for quite a while without finding anything that actually works. My current code can be seen here:

 void OnControllerColliderHit(ControllerColliderHit hit){
              if(hit.gameObject.name == "JumpBoost"){
                 Debug.Log("Hit");
                 transform.Translate(new Vector3(0,10F,0)*Time.deltaTime);
     
             }
         }

Right now it just jumps up and down extremely fast, and ain't getting much more than a few centimeters up in the air. Can anyone tell me how I get a more "smooth" jump?
