EV24881-S-00A

EV24881-S-00A is an evaluation board designed for the MP24881, a 60V, monolithic, synchronous step-down LED driver with a built-in power N-channel MOSFET and rectifier. It delivers up to 1.1A of continuous output current (IOUT) to high-power LEDs. The wide 10V to 60V input voltage (VIN) range accommodates a variety of step-down lighting applications. Hysteretic current mode control achieves very fast transient response and eliminates the need for loop compensation design. The MP24881 supports analogue dimming and implements down to a 3% dimming depth. It also supports analogue dimming with a pulse width modulation (PWM) signal input, which removes the flicker caused by the PWM frequency. This dimming depth can also be 3%. The separated PWM and analogue signal inputs achieve and simplify hybrid dimming. This feature also allows all PWM signals to be controlled by hybrid dimming, with a dimming depth down to 0.1%.

• Output current (IOUT) is 700mA
• Typical efficiency is 98% at VIN = 40V, VOUT = 35V, IOUT = 700mA

MPS part numbers ending in "-P" and "-Z" are the same parts. P & Z only indicates reel size.
