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
—DC-DC Step Down Regulator 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
Protection (OCP), Short-Circuit Protection (SCP) functions
Input voltage and output current range for the evaluation Board are given in Table 1.
1.3 Applications
—Portable appliance, etc
1.4 Package

1.6 Simplified Application Circuit
Notes) yThis application circuit is an example. The operation of mass production set is not guaranteed. You should perform enough evaluation and
verification on the design of mass production set. You are fully responsible for the incorporation of the above application circuit and
information in the design of your equipment.
yThis block diagram is for explaining functions. Part of the block diagram may be omitted, or it may be simplified.
