MP24893

Step Down White LED Driver

with Wide 6V-to-36V Input Voltage

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP24893 is a high efficiency step-down

converter designed in continuous current mode

for driving the high brightness LEDs from wide

input voltage of 6V to 36V.

•

Internal 36V MOSFET

Wide 6V-to-36V Input Range

1A Output Current

High Efficiency

Hysteretic Control

PWM and Analog Dimming

1000:1 PWM Dimming Resolution

UVLO, Thermal Shutdown

Available in TSOT23-5 and QFN6 Packages

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.

APPLICATIONS

•

Low-Voltage Halogen Replacement

Low-Voltage General Illumination

Automotive/Decorative LED Lighting

Signs/Emergency Lighting

The MP24893 implements PWM and analog

dimming together through the DIM pin.

LED Backlighting

The MP24893 includes under-voltage lockout,

thermal overload protection to prevent damage

in the event of an output overload.

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

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

page.
