【文字介紹】

The MP24892 employs a hysteretic control
architecture to regulate a high-accuracy LED
current, which is measured through an external
high-side current-sensing resistor. Provides optimal circuit stabilization and a very quick response time without loop compensation.
Its low 202mV average feedback voltage reduces power loss and improves the converter efficiency.
The MP24892 implements PWM and analog
dimming together through the DIM pin.
It's includes thermal overload protection that prevents damage in the event of an output overload.
The MP24892 is available in a small TSOT23-5
package.
