DESCRIPTION

The MP2410A is a 24V, monolithic, synchronous,

step-down, white LED driver with a built-in power

MOSFET and rectifier. It achieves up to 2A of

continuous output current with excellent load and

line regulation. Peak current mode operation

provides fast transient response and eases loop

stabilization.

The MP2410A incorporates both analog and

PWM dimming onto a single control pin. The

MP2410A implements deep analog dimming and

PWM dimming.

Full protection features include cycle-by-cycle

peak-current

limiting,

output

short-circuit

protection (SCP), open LED protection, NTC

thermal protection, and thermal shutdown.

The MP2410A requires a minimum number of

readily available, standard, external components

and is available in TSOT23-6 and TSOT23-8

packages.
