MP2489是一个Step-Down White LED Driver with Wide 6V---60V Input Voltage ，其采用QFN-10 SOT-6的引脚封装
其具体引脚封装如下：
Description：
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 3x3mm 8-pin QFN and TSOT23-5 packages.
