1.2A(IOUT), 1.5MHz High Input Voltage Switching Regulator with Programmable Output Current Limit

Linear Technology has announced the LT3663, a 1.2A, 1.5MHz monolithic current mode step-down switching regulator with a programmable output current limit. Its wide operating input voltage of 7.5V to 36V makes the LT3663 ideal for a variety of input sources, including unregulated 12V wall adapters, 24V industrial supplies, Fire Wire, as well as automotive applications. Onboard input overvoltage lockout protects the device through input transients as high as 60V, such as those commonly found in automotive applications.
