The LM5008MM is a step-down DC/DC buck switching regulator designed for high-voltage applications, with an input voltage range of 9.5V to 95V and a maximum output current of 350mA. It features an integrated 100V N-channel buck switch and operates with a constant frequency between 50kHz and 600kHz. The regulator employs a hysteretic control scheme that eliminates the need for loop compensation, ensuring fast transient response and stable operation across varying line voltages and load currents. The output voltage is adjustable, with a minimum output voltage of 2.5V and a maximum of 75V. Protection features include thermal shutdown, intelligent current limit, and undervoltage lockout. The device is available in both 8-pin VSSOP and WSON packages, making it suitable for compact designs. It is commonly used in telecommunications, automotive systems, and power management applications.
