MP3378

24 V, 4-Channel WLED Controller

Plus High-Efficiency Buck Converter

DESCRIPTION

FEATURES

The MP3378 is a one-chip solution designed for

monitor applications. It includes a step-up

WLED Controller:



4-String, Max 350 mA/String WLED

Controller

controller with

current channels for

a high-efficiency buck

backlighting and



Up to 24 V Input Voltage Range

2.5% Current Matching Accuracy

Programmable Switching Frequency

PWM and Analog Dimming Mode

Open and Short LED Protection

Programmable Over-Voltage Protection

Recoverable Thermal Shutdown Protection

Over-Current Protection

converter for internal bus voltage or standby

power.

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 the special dimming mode request. In

addition, rich protection modes are integrated

including OCP, OTP, UVP, OVP, LED

short/open protection, and inductor/diode short

protection.

Over-Temperature Protection

Inductor/Diode Short Protection

Buck Converter:



144 mΩ/58 mΩ Low Rds(on) Internal Power

MOSFETs

The high-efficiency buck converter operates in

current mode with a built in MOSFET and

synchronous rectifier. It offers a very compact

solution to achieve excellent load and line

regulation. Full protection features include OCP

and thermal shutdown.



Low Quiescent Current

Fixed 235 kHz Switching Frequency

Frequency Sync from 250 kHz to 2 MHz

External Clock

AAM Power-Save Mode

Internal Soft Start

OCP and Hiccup

Over-Temperature Protection

Output Adjustable from 0.8 V



The MP3378 is available in SOIC28 and

TSSOP28EP package.

APPLICATIONS



Desktop LCD Flat Panel Displays

Flat Panel Video Displays

2D/3D LCD TVs and Monitors
