TPS657120 Overview
The TPS657120 provides three configurable step-down converters with up to 2-A output current.This device also has 2 LDO regulators. LDO1 can be supplied from either the input voltage directly or from a pre-regulated supply such as DCDC1 or DCDC2. The input voltage to LDO2 is used as an analog supply input and therefore must be tied to the input voltage at the same voltage level with VINDCDC1/2 and VINDCDC3.
