.. Features n LT3653 1.2A, HV Input Regulator with Output Current Limit for Battery Charger Applications DESCRIPTION The LT®3653 is a monolithic current mode PWM step-down regulator with programmable output current limit. Typically, it is used with battery charger power path controllers to pre-regulate the output and optimize the battery charger efficiency. Output current limit provides accurate control over system power dissipation. The wide operating input voltage range of 7.5V to 30V suits the LT3653 to a variety of input sources, including unregulated 12V wall adapters, 24V industrial supplies, Firewire and automotive power. Input overvoltage protection allows the...
