1 Introduction
This user’s guide contains background information for the
AN30182A : Multi Power Supply (High Efficiency Power LSI)
as well as support documentation for the AN30182A Evaluation Board (AN30182A-EVB). Also included are the schematic, the bill of
materials and the Board Layout for the Evaluation Board.
1.1 Overview
AN30182A is a multi power supply LSI which has high-speed response DC-DC Step Down Regulators (2-ch) and LDO Regulators
(6-ch).
The output DC of each power supply is variable by I2C control.
1.2 Features

2-ch
(Output voltage 0.8 V to 2.4 V,
Output current 600 mA)
—Regulator
6-ch
(Output voltage 1.0 V to 3.3 V,
Output current 300 mA)
—I2C control
(2-slave address selectable)
—Input Voltage Range: VBAT: 2.5V~ 5.5V , DVDD: 1.7V ~ 3.0V
—Built-in Under Voltage Lockout (UVLO), Thermal Shut Down (TSD), Output Over-Current
