The Future of Analog IC Technology
The MP24892 is a high-efficiency step-down
converter that functions in continuous current
mode to drive high-brightness LED. It can take
a wide input voltage range of 6V–45V.
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. Moreover,
this control scheme 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.
The MP24892 includes thermal overload
protection that prevents damage in the event of
an output overload.
The MP24892 is available in a small TSOT23-5
