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.
