The EV24833-A-N-00AEvaluation Board is designed to demonstrate the capabilities of MP24833-A. The MP24833-A is a 55V, 3A, white LED driver suitable for either step-down or inverting step‑up/down applications.

EV24833-A-N-00A is compatible with step-down (Buck) and inverting step-up/down (Buck-boost) applications.

  • For step-down application, short “JP1”, open “JP2”, connect LED load to “LED+” and “LED-”
  • ; For step-up/down application, short “JP2”, open “JP1”, connect LED load to “LED+” and “LED-”


  • 3A Maximum Output Current
  • Unique Step-Up/Down Operation (Buck-Boost Mode)
  • Wide 4.5V-to-55V Operating InputRangefor Step-Down Applications (Buck Mode)
  • 0.19Ω Internal Power MOSFET Switch
  • Fixed 200kHz Switching Frequency
  • Analog and PWM Dimming
  • 0.198V Reference Voltage
  • 6μA Shutdown Mode
  • No Minimum Number of LEDs Required
  • Stable with Low ESR Output Ceramic Capacitors
  • Cycle-by-Cycle Over-Current Protection
  • Thermal Shutdown Protection
  • Open Strings Protection
  • Output Short-Circuit Protection
  • Available in an SOIC8EP Package


  • IC Supported 1MP24833-A




The MP24833A is a 55V, 3A, white LED driver suitable for step-down, inverting step up/step-down, and step-up applications. The MP24833-A achieves 3A of output current with excellent load and line regulation over a wide input supply range. Current mode operation provides a fast transient response and eases loop stabilization. Full protection features include thermal shutdown, cycle­by­cycle peak current limiting, open-string protection, and output short-circuit protection (SCP). The MP24833A incorporates both DC and PWM dimming into a single control pin. The separate input reference ground pin allows for direct enable and/or dimming control for a positive-to-negative power conversion. The MP24833A requires a minimal number of readily available, standard, external components and is available in a SOIC-8 EP package.
