Multitopology, High Power, VIN to 100V, Accurate ISENSE

Linear’s next generation boost controllers and regulators are so versatile, they can easily be configured for boost, flyback, SEPIC, LED driving and inverting power supply topologies. Features include input voltages up to 100V and very accurate current sense thresholds. These controllers can regulate a positive or negative output voltage via a single feedback pin and have overload protection.
