Automotive Switching Regulators

ROHM Semiconductor Automotive Switching Regulators are AEC-Q100 qualified power management ICs. These ROHM Semiconductor switching regulators consist of regulators with or without integrated FET, buck converters (both synchronous and nonsynchronous), and buck-boost converters. Automobile switching regulators are available from single-channel to multi-channel system power supply configurations for broad compatibility. These switching regulators come in various packages with built-in circuit protection functions to match the requirements of the designers.

BD9S Series Automotive Buck DC-DC Converters

ROHM Semiconductor BD9S Automotive Buck DC-DC Converters provide high-reliability and low power consumption in a compact form factor with a temperature range of -40°C to +125°C. The BD9S DC-DC Converters feature current-mode control, ensuring fast response to load transients. A fixed 2.2MHz switching frequency prevents interference in the AM Band. This high frequency also allows the use of smaller external components, contributing to a higher degree of miniaturization and power savings. The BD9S Converters also include an enable function to adjust the startup time and a built-in output (Power Good function) indicating correct output voltage has been achieved. These AEC-Q100 qualified (Grade 1) devices support output currents from 0.6A to 4.0A for design flexibility.
