1 Introduction

The LP8764x-Q1 power management integrated circuit (PMIC) family is extremely flexible and scalable, providing configurability at the device and system level. At the device level, a single PMIC can provide up to four separate step down converters (buck regulators). These buck regulators can be used in multiphase mode to provide a single 20 A source. At the system level, several PMICs can be configured to work in a controller-target topology with one controller and up to five target PMICs. The LP8764x-Q1 evaluation module (EVM) is both an evaluation and development tool. With the EVM both device level and system level configurability are available through an easy to use graphical user interface (GUI) tool.

Table 1-1 shows the available controller and target EVMs, the silicon associated with those EVMs, the initial non-volatile memory (NVM) configuration, and the hardware components associated with the configurations. Because of the configurable nature of both the part and the EVM, any EVM can be configured as a controller or target device.
