ROHM’s BD9G341AEFJ is a buck switching regulator with integrated 150 mΩ power MOSFET. Current-mode architecture provides fast transient response and a simple phase compensation setup. The operating frequency is programmable from 50 kHz to 750 kHz. Additional protection features, such as over-current protection (OCP), thermal-shutdown (TSD), and under-voltage lockout (UVLO), are included. The UVLO and hysteresis can be set by external resistor.
