ROHM has announced new step-down switching regulators with a built-in 800mOhm Power MOSFET. The BD9G101G series provides 0.5A DC output with excellent line and load regulation for smart power management in a small SOT23 (SSOP6) package. The operating frequency is fixed at 1.5MHz, allowing the use of a small inductor and a ceramic capacitor in order to reduce space requirements. All phase compensation components are integrated as well.
The input voltage can vary from 6 to 42V, the internal reference voltage is set to 0.75V with an accuracy of typical ±1.5%. Ideally suited to facilitate step-down switching designs, the new device offers first-rate thermal resistance and multiple protection features such as internal over current protection, under voltage locked out and thermal shutdown. The operating temperature spans from -40°C to +105°C while the maximum junction temperature lays at 150°. Areas of deployment are industrial distributed power and automotive applications, battery powered equipment and medical OA instruments. Some of the key features are: - High and Wide Input Range (VCC=6V to 42V) - 45V/800mOhm Internal Power MOSFET - 1.5MHz Fixed Operating Frequency - Feedback Pin Voltage 0.75V±1.5% - Internal compensated - Internal Over Current protection, Under Voltage Lock Out, Thermal shutdown - 0µA Shutdown Supply Current - 6-Lead SOT-23 package (SSOP6)

In recent years Silicon Carbide (SiC) has emerged as one of the most viable candidates in the search for a next-generation, low-loss power semiconductor element due to its low ON resistance and superior high temperature, high frequency.
ROHM has released a new sensor shield (expansion board) equipped with 8 sensor boards (e.g. accelerometer, barometric pressure, geomagnetic, heart rate sensors, etc.) designed for use with existing open platform MCUboards such as Arduino, and mbed.
ROHM has launched a 12 to 76V input, 3A variable output voltage, DC/DC Buck converter with integrated 76V MOSFET optimized for high power (high voltage x large current) applications such as motors, factory automation equipment, communications
