Linear Technology Corporation announces the LT3653, a 1.2A, 1.5MHz monolithic current mode step-down switching regulator with a programmable output current limit. Typically, it is used with battery charger power path controllers to pre-regulate the output and optimize battery charger efficiency. Its wide operating input voltage of 7.5V to 30V makes the LT3653 ideal for a variety of input sources including unregulated 12V wall adapters, 24V industrial supplies and Firewire 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. |
