STMicroelectronics L6716

Description

The device implements a two-to-four phases step down 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
requirements. The device embeds VR11.x DACs: the output voltage ranges up to 1.60000 V managing D-VID with ± 0.5 % output voltage accuracy over line and temperature variations.
