The EV2489DQ-01A is an evaluation board for the MP2489DQ, a step-down converter designed in continuous current mode for driving the high brightness light emitting diodes (LEDs) from wide input voltage 8V-36V. If higher input voltage (up to 60V) is required, use B190 instead of B140 in D1-D5.
The MP2489 employs hysteretic control architecture to regulate a high accuracy LED current, which is measured through an external high-side current sensing resistor. Moreover, this control scheme provides optimized circuit stabilization and very quick response time without the loop compensation. Its low 200mV average feedback voltage reduces power loss and improves the converter efficiency.
The MP2489 implements PWM and Analog Dimming with DIM pin. The MP2489 includes under-voltage lockout function, thermal overload protection preventing damage in the event of an output overload.
