Today, while i was desoldering some parts from a laptop motherboard i came across a strange chip, at least strange for me because i never saw anything like this before. The chip is labeled LF-H80P, i did a quick search on google but nothing interesting showed up.

At first glance, the chip looks perfectly normal, but when you look on it’s back you can see four inductance windings:
