Sean Dyche's side were slow to get going on Saturday at home to Aston Villa, falling 1-0 behind to Joe Cole's first-half goal.
But last season's Championship runners-up responded strongly after the interval, and eventually drew level through Ings' penalty three minutes from time.
"The lads are confident at the moment, we've got to take confidence out of the last three games," he told Burnley's official website.
"The Premier League is the toughest league in the world and we're really competing now so it's well done to the boys.
"Last year we were always good under the lights on a Tuesday night so it's going to be tough for Newcastle to come here and put on a performance against us.
"But we can't start like we did [against Villa]. With all due respect I think they [Newcastle] have got more quality than the team we played [on Saturday].
"So it's important that we're on the front foot and we take the game to them."
Alan Pardew, meanwhile, will be without Moussa Sissoko, who was sent off in Saturday's 1-0 defeat to West Ham, and Jack Colback, after he was shown a fifth yellow card of the season at Upton Park.
"This is football and we will take the good parts of our performance into Tuesday night at Burnley," he told the club's official website.
"It is important to remember that we won our last six games. We are in a good position, in good condition and if we win on Tuesday then one defeat in this game is not too bad.
"We will do everything we can to come back against Burnley - it is a very important game."
