BD9851EFV

TECHNICAL NOTE Large Current External FET Controller Type Switching Regulators Single-output High-frequency Step-down Switching Regulator(Controller type) BD9850FVM Dual-output Step-up, Negative, Step-down Switching Regulator(Controller type) BD9851EFV High temperature operating Now available ESD Resistance Now available Description The BD9850FVM is a 1-channel DC/DC step-down switching regulator controller, while the BD9851EFV is a 2-channel DC/DC step-down switching regulator controller. The BD9850FVM is adaptable for a maximum switching frequency of 2 MHz and the BD9851EFV for that of 3 MHz. Both provide space saving in all applications. Features 1) Adaptable for 2-MHz switching frequency (externally variable) (BD9850FVM) Adaptable for 3-MHz switching frequency (externally variable) (BD9851EFV) 2) FET direct drive 3) High-accuracy reference voltage (Accuracy: ±1%) 4) Built-in Under Voltage Lock Out circuit (UVLO) 5) Built-in Thermal Shutdown circuit (TSD) 6) The BD9851EFV prov...
