Monolithic Power Systems MP2489
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. Its low 202mV average feedback voltage reduces power loss and improves the converter efficiency.| Part No. | MP2489 |
