Step Down White LED Driver

–

with Wide 6V 45V Input Voltage

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP24892 is a high-efficiency step-down

converter that functions in continuous current

mode to drive high-brightness LED. It can take

a wide input voltage range of 6V–45V.



Wide 6V-to-45V Input Range

1A Output Current

High Efficiency (>95%)

Hysteresis Control

PWM & Analog Dimming

1000:1 PWM Dimming Resolution

Thermal Shutdown

Inherent Open LED Protection

Short LED Protection

The MP24892 employs a hysteretic control

architecture to regulate a high-accuracy LED

current, which is measured through an external

high-side current-sensing resistor. Moreover,

this control scheme provides optimal circuit

stabilization and a very quick response time

without loop compensation. Its low 202mV

average feedback voltage reduces power loss

and improves the converter efficiency.

Available in a TSOT23-5 Package

APPLICATIONS



Low-Voltage Halogen Replacement

Low-Voltage General Illumination

Automotive/Decorative LED Lighting

Signs/Emergency Lighting

The MP24892 implements PWM and analog

dimming together through the DIM pin.

The MP24892 includes thermal overload

protection that prevents damage in the event of

an output overload.

LED Backlighting

All MPS parts are lead-free and adhere to the RoHS directive. For MPS

green status, please visit MPS website under the Products, Quality

Assurance page.

The MP24892 is available in a small TSOT23-5

package.
