Introduction
NEW! AN3018xA Series
Multi-Channel DC/DC Step-Down Regulator with Integrated FET and LDO
Fast Response, Small Size, I2C Control
Panasonic, a worldwide leader in Semiconductor Products, introduces the New AN3018xA Series
Multi-Channel DC/DC Step-Down Regulators with Integrated FET and LDO. The New AN3018xA
Series parts offer a power management LSI Step-Down DC/DC Regulator (1 to 2ch) that uses
Panasonic’s original Hysteretic DC/DC core control system. By employing this system, when the load
current changes suddenly, the New AN3018xA Series parts respond at high speed and minimize output
voltage changes. Since it is possible to use capacitors with small capacitance and it is unnecessary to
use parts for phase compensation, these IC’s allow for downsizing of set and a reduction in the number
of external parts. Output voltages are variable by DAC (0.8 to 3.3 V) and maximum current is up to 1.2
A. This LSI has a LDO circuit which output voltage and can change by DAC (0.9 to 3.3V) and maximum
current up to 0.3 A.
Features:
• High-Speed Response
• Output Voltage Range: 0.8V to 3.3V
• Input Voltage Range: 2.9V to 5.5V (Can be
supported by Panasonic Li-Ion Battery)
• High Efficiency Over a Wide Load Current Area by
DCM (Discontinuous Conductive Mode) Opera-
tion at Light Loads, CCM (Continuous Conductive
Mode) Operation in Heavy Loads
• DCM and CCM Can Be Automatically Switched
• Switching Frequency: 3.0MHz during CCM
• 100% Duty Operation When Input Voltage Equals
Output Voltage
• I2C Control for ON/OFF and Output Voltage
DAC Setting (DC/DC and LDO)
• 2-Slave Address Selectable
• Small Size (WLCSP):1.5mm x 4 mm Square
• Built-In Under Voltage Lockout (UVLO), Thermal
Shut Down (TSD), Output Over-Current Protection
(OCP), Short-Circuit Protection (SCP) Functions
