The Future of Analog IC Technology DESCRIPTION The MP24895 is step-down LED driver, which is designed in continuous current mode for driving the high-brightness LEDs from a wide input voltage of 6V to 36V. The MP24895 employs a hysteretic control scheme to regulate LED current. Moreover, the control scheme provides optimal loop stabilization and a very quick response time. For a high accuracy, the MP24895 senses LED current by an external high-side resistor. Its low 100mV average feedback voltage reduces power loss and improves the efficiency. The MP24895 implements PWM and analog dimming together on the EN/DIM pin. The MP24895 includes under-voltage lockout,t and thermal overload protection to prevent damage in the event of an output overload.
