Output 12.5 V / 2 A
IC revision003

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/3.3 V. 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 (Simple Light Load Mode)
  • Soft-Start Function
  • Thermal Shutdown and UVLO Functions
  • Short-Circuit Protection with Time Delay Function
  • Shutdown Function

Typical applications

  • Power Supply for LSI including DSP, Microcomputer and ASIC
