DESCRIPTION
The EV24893DJ-00A is an evaluation board for
the MP24893DJ, a step-down converter
designed in continuous current mode for driving
the high brightness LEDs from wide input
voltage of 6V to 30V.
The MP24893 employs hysteretic control
architecture to regulate a highly accurate LED
current, which is measured through an external
high-side current-sense resistor. Moreover, this
control scheme provides optimal circuit
stabilization and a very quick response time
without loop compensation. Its low 200mV
average feedback voltage reduces power loss
and improves the converter efficiency.
The MP24893 implements PWM and analog
dimming together through the DIM pin. The
MP24893 includes under-voltage lockout,
thermal overload protection to prevent damage
in the event of an output overload.
