MP3378E

4-Channel WLED Controller

with High-Efficiency Buck Converter

DESCRIPTION

FEATURES

The MP3378E is a one-chip solution specially

designed for monitor applications. The

MP3378E includes a step-up WLED controller

with four current channels for backlighting, and

a high-efficiency buck converter for internal bus

voltage or standby power.

WLED Controller:



4-String,

Controller

Max

350mA/String,

WLED



Up to 24V Input Voltage Range

2.5% Current Matching Accuracy

Programmable Switching Frequency

PWM and Analog Dimming Mode

LED Open and Short Protection

Programmable Over-Voltage Protection

Recoverable Thermal Shutdown Protection

Over-Current Protection

The 4-string WLED controller drives an external

MOSFET to boost up the output voltage from

the input supply. It regulates the current in each

LED string to the programmed value set by an

external current setting resistor. It supports both

analog and PWM dimming independently to

meet special dimming mode requests. Full

protection features for the WLED controller

include OCP, OTP, UVP, OVP, LED short/open

protection, and inductor/diode short protection.

Over-Temperature Protection

Inductor/Diode Short Protection

Buck Converter:



144mΩ/80mΩ Low R_DS(ON)Internal Power

MOSFETs

The high-efficiency buck converter operates in

the current mode operation with a built-in

MOSFET and a built-in synchronous rectifier. It

offers a very compact solution to achieve

excellent load and line regulation. Full

protection features for the buck converter

include OCP and thermal shutdown.



Low Quiescent Current

Fixed 235kHz Switching Frequency

Frequency Sync from 250kHz to 2MHz

External Clock

Internal Soft Start

OCP and Hiccup Mode

The MP3378E is available in a TSSOP-28 EP

package.

Over-Temperature Protection

Output Adjustable from 0.8V

APPLICATIONS



Desktop LCD Flat Panel Displays

Flat Panel Video Displays

2D/3D LCD TVs and Monitors
