Beschreibung
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.
Eigenschaften
- 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
Typische Anwendungen
- Power Supply for LSI including DSP, Microcomputer and ASIC
