Buck switching regulator with integrated 150mohm power MOSFET

Rohm's BD9G341AEFJ buck converter integrated FET is now available from Mouser stock. The buck switching regulator integrates a 150mohm power MOSFET and its current mode architecture provides fast transient response and a simple phase compensation setup. The operating frequency is programmable from 50kHz to 750kHz. Additional protection such as over-current protection, thermal shutdown and under-voltage lockout are provided. The under-voltage lockout and hysteresis can be set by an external resistor.
