Features: MP24895A 6V - 36V, Step-Down, White LED Driver DESCRIPTION The MP24895A is ste p-down LED driver designed in continuou s current mode for driving the high-bri ghtness LEDs from a wide input voltage of 6V to 36V. The MP24895A employs a hy steretic control scheme to regulate the LED current. This control scheme provi des optimal loop stabilization and a ve ry quick response time. For high accura cy, the MP24895A senses the LED current by an external high-side resistor. Its low 100mV average feedback voltage red uces power loss and improves efficiency . The MP24895A implements pulse-width m odulation (PWM) and analog dimming on E N/DIM. Full protection features include under-voltage lockout (UVLO) and therm al overload protection to prevent damag e in the event of an output overload. T he MP24895A is available in an MSOP-8 E P package. TYPICAL APPLICATION FEATURE S  Internal 36V MOSFET  Wide 6V t o 36V Input Range  1A Output Current  High Efficiency  Hysteretic Control  PWM and Analog Dimming  10.

MP24895A
6V - 36V, Step-Down,
White LED Driver
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.
