The L6716 is a DC-DC converter from STMicroelectronics that supports 2/3/4 phase control, an internal driver, and Intel VR11.1 standards. It features Load Transient Boost Technology, which minimizes the number of output capacitors, and provides 0.5% output voltage accuracy, 8-bit programmable output up to 1.60000 V, support for LSLess startup to manage pre-biased output, and feedback disconnection protection, preliminary over voltage protection, programmable over current protection, programmable over voltage protection, adjustable switching frequency, SS_END and OUTEN signals.
The document describes the L6716, a two-to-four phases step-down controller featuring three integrated high current drivers in a compact VFQFPN-48 package. It is designed for high-current VRM/VRD applications for desktop and server CPUs.
Key features include Load Transient Boost (LTB) technology to minimize output capacitors, support for Intel VR11.1 DACs with backward compatibility, full differential current sensing, and programmable protection strategies such as overcurrent and overvoltage.
