The Future of Analog IC Technology
DESCRIPTION
The MP24895 is step-down LED driver, which
is designed in continuous current mode for
driving the high-brightness LEDs from a wide
input voltage of 6V to 36V.
The MP24895 employs a hysteretic control
scheme to regulate LED current. Moreover, the
control scheme provides optimal loop
stabilization and a very quick response time.
For a high accuracy, the MP24895 senses LED
current by an external high-side 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,t
and thermal overload protection to prevent
damage in the event of an output overload.
The MP24895 is available in TSOT23-5 and
QFN-6 packages.
