MP4001

Universal Input High Brightness

White LED Driver

The Future of Analog IC Technology

DESCRIPTION

The MP4001 is a high efficiency step-down

converter designed for driving the high

brightness Light Emitting Diodes (LEDs).

FEATURES

•

Constant-current LED Driver

Universal AC Input (85VAC-305VAC)

Power MOSFET Zero-Current Turn On

High Efficiency Boundary Mode Operation

Integrated High-voltage Smart LDO

Low 1mA Operation Current

PWM or DC Input Burst Dimming Control

Hiccup Short Circuit Protection

Maxim Frequency Limited to 110kHz

Thermal Shutdown

The MP4001 drives external MOSFET with

boundary conduction mode which features no

reverse recovery loss in the freewheeling diode,

soft turn on with zero-current and valley voltage

for the power MOSFET. Such operation mode

can achieve very high efficiency and in the

same time minimize the inductor value and size.

With the boundary conduction control mode, the

LED current can be well regulated by control

the MOSFET peak current which is sensed

through an external resistor. Its low 300mV

feedback voltage reduces power loss and

improves the efficiency.

Available in SOIC8 Package

APPLICATIONS

•

Non-Isolated Lighting

General Illumination

Industrial Lighting

Automotive/ Decorative LED Lighting

LCD TV Backlighting

The MP4001 integrates a high-voltage smart

LDO, which allows the AC input to power up the

IC directly. The smart LDO sinks current when

the input voltage is lower than 24V to achieve

higher efficiency.

DC/DC or AC/DC LED Driver Applications

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.

“MPS” and “The Future of Analog IC Technology” are Registered Trademarks of

Monolithic Power Systems, Inc.

The MP4001 implements both PWM and DC

input burst dimming The MP4001 features

output short protections, maximum switching

frequency limitation, under-voltage lockout and

thermal shut down.
