DESCRIPTION

The

MP24895A

is

step-down

LED

driver

designed in continuous current mode for driving

the high-brightness LEDs from a wide input

voltage of 6V to 36V.

The MP24895A employs a hysteretic control

scheme to regulate the LED current. This

control

scheme

provides

optimal

loop

stabilization and a very quick response time.

For high accuracy, the MP24895A senses the

LED current by an external high-side resistor.

Its

low

100mV

average

feedback

voltage

reduces power loss and improves efficiency.

The

MP24895A

implements

pulse-width

modulation (PWM) and analog dimming on

EN/DIM.

Full protection features include under-voltage

lockout (UVLO) and thermal overload protection

to prevent damage in the event of an output

overload.

The MP24895A is available in an MSOP-8 EP

package.
