Product Description

The EV24895-Q-00A is an evaluation board for the MP24895GQ, a step-down converter designed in hysteretic current control mode for driving the high brightness LEDs from wide input voltage of 9V to 30V.

The MP24895 employs hysteretic control architecture to regulate LED current. Moreover, this control scheme provides optimal circuit stabilization and a very quick response time without loop compensation. The highly accurate LED current is measured through an external high-side current-sense 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, and thermal overload protection to prevent damage in the event of an output overload.

IC Details

The MP2489 is a high efficiency step-down converter designed in continuous current mode for driving the high brightness Light Emitting Diodes (LED) from wide input voltage 6V–60V. 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 202mV average feedback voltage reduces power loss and improves the converter efficiency.  The MP2489 implements PWM and analog dimming together with DIM pin.  The MP2489 includes thermal overload protection preventing damage in the event of an output overload.  The MP2489 is available in small QFN6 (3x 3mm), TSOT23-5 and SOIC8E packages.
