Ultra high-efficiency buck switching regulator integrates 150mohm power MOSFET

Rohm's BD9G341AEFJ ultra high-efficiency buck 80V DC-DC switching regulator with integrated 150mohm power MOSFET is now available from Digi-Key. The device's current-mode architecture provides fast transient response and a simple phase compensation setup. The operating frequency is programmable from 50kHz 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.
