MP3393

8-String Step-Up White LED Driver

with External Transistor

The Future of Analog IC Technology

DESCRIPTION

The MP3393 is a step-up controller with 8

current channel sources designed to power

WLED backlights for large LCD panels.

FEATURES

•

9V-to-32V Input Voltage Range

Drives 8 Channels of LED strings

Internal Constant-Current Control

Maximum Channel Current Over 350mA

1.2% Current Matching Accuracy Between

Strings

The MP3393 uses current-mode fixed-frequency

architecture. It drives an external MOSFET to

boost the output voltage. The switching frequency

is programmable by an external setting resistor.

•

Programmable Switching Frequency

Analog Dimming and External PWM

Dimming

The MP3393 integrates a constant-current control

circuit to regulate the current in each LED string

to the value set by an external current feedback

resistor. Current matching can achieve 1.2%

regulation accuracy between strings. Its low

202mV regulation voltage reduces power loss

and improves efficiency.

•

Open and Short LED Protection

Programmable Over-Voltage Protection

Fault Output Flag

Thermal Shutdown

Extendable LED Channels that Share One

Power Stage Set

The MP3393 includes protections including

under-voltage lockout, LED open/short protection,

and thermal shutdown. The fault flag pin indicates

the statuses of all fault signals.

•

TSSOP28EP and SOIC28 Packages

APPLICATIONS

•

Flat Panel Video Displays

LCD TVs and Monitors

The MP3393 can be daisy-chained to expand

the number of LED channels. It is available in

TSSOP28EP and SOIC28 packages.

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

status, please visit MPS website under Quality Assurance.
