N-channel controller for constant current LED drivers, featuring a series DIM FET driver and fault flag. Operates with input voltages from 4.5V to 75V, supporting output voltages up to 72V. This surface mount component, housed in a 20-pin HTSSOP package (4.4mm width, 6.5mm length, 0.9mm height), offers a 2MHz operating frequency and a maximum supply current of 3.5mA. Suitable for Buck-Boost and SEPIC topologies, it functions across a wide temperature range of -40°C to 125°C.
