2.7V to 5.5V, 2.0A 1ch

Synchronous Buck Converter with

Integrated FET

BD9130NV

General Description

BD9130NV is ROHM’s high efficiency step-down

switching regulator designed to provide a voltage as

low as 1V from a supply voltage of 5.5V/3.3V. It offers

high efficiency by using pulse skip control technology

and synchronous switches, and provides fast transient

response to sudden load changes by implementing

current mode control.

Features

 Fast Transient Response because of Current Mode

PWM Control System

 High Efficiency for All Load Ranges because of

Synchronous Switches (Nch/Pch FET) and SLLM

TM

(Simple Light Load Mode)

 Soft-Start Function

 Thermal Shutdown and UVLO Functions

 Short-Circuit Protection with Time Delay Function

 Shutdown Function

Applications

Power Supply for LSI including DSP, Microcomputer

and ASIC

Key Specifications

 Input Voltage Range: 2.7V to 5.5V

 Output Voltage Range: 1.0V to 2.5V

 Output Current: 2.0A (Max)

 Switching Frequency: 1MHz(Typ)

 Pch FET ON-Resistance: 200mΩ(Typ)

 Nch FET ON-Resistance: 160mΩ(Typ)

 Standby Current: 0μA (Typ)

 Operating Temperature Range: -25°C to +105°C

Package W(Typ) x D(Typ) x H(Max)
