General Description

The BD9139MUV is ROHM’s high efficiency step-down switching regulator designed to produce a voltage as low as 0.8V 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.

Key Features

Fast Transient Response because of Current Mode PWM Control System.
High Efficiency for All Load Ranges because of Synchronous Switches (Nch/Nch FET) and SLLMTM (Simple Light Load Mode).
Soft-Start Function.
Thermal Shutdown and UVLO Functions.
Short-Circuit Protection with Time Delay Function.
Shutdown Function Key Specifications.
Input Voltage Range:.
Output Voltage Range:.
Output Current:.
Switching Frequency:.
High Side FET ON-Resista.
