L6716 2/3/4 phase step-down controller

The device implements a two-to-four phases stepdown controller with three integrated high current drivers in a compact 7x7 mm body package with exposed pad. Load transient boost LTB Technology™ reduces system cost by providing the fastest response to load transition therefore requiring less bulk and ceramic output capacitors to satisfy load transient require.
