The MP24881 is a 60V, monolithic, synchronous step-down LED driver with an integrated N-channel MOSFET and rectifier. It delivers up to 1.1A of continuous LED current (ILED) to high-power LEDs. The wide 10V to 60V input voltage (VIN) range accommodates a variety of step-down lighting applications. Hysteretic current mode minimizes the loop compensation design and achieves fast transient response, which makes the 25kHz pulse-width modulation (PWM) dimming frequency possible.\n\n The MP24881 supports analog dimming with a PWM or analog signal input, which helps remove the flicker caused by the PWM frequency (fPWM). The separated PWM and analog dimming input port enables all PWM signal-controlled hybrid dimming. The hybrid dimming depth can reach as low as 0.1%.\n\n Full protections include current-sense (CS) short protection, low-side (LS) reverse over-current protection (OCP), high-side (HS) OCP, and thermal shutdown.\n\n The MP24881 is available in an SOIC-8EP package.\n\n
