MPQ3367

6-Channel, Max.150mA/Ch

Boost WLED Driver

with 15000:1 Dim Ratio and I²C

FEATURES

DESCRIPTION

•

3.5V to 36V Input Voltage Range

6 Channels with Max. 150mA per Channel

Internal 100mΩ, 50V MOSFET

Programmable Up to 2.2MHz f_SW

External Sync SW Function

Multi-Dimming Operation Mode through

PWM Input, Including:

The MPQ3367 is a step-up converter with 6

channel current sources, designed to drive the

white LED arrays as backlighting in small-to-mid-

size LCD panels.

The MPQ3367 uses peak current mode as its

PWM control architecture to regulate the boost

converter. Six channel current sources are

applied into the LED cathode to adjust the LED

brightness. The MPQ3367 regulates the current

in each LED string to the value set by an external

current-setting resistor, with 2.5% current

regulation accuracy between strings.

o Direct PWM Dimming

o Analog Dimming

o Mix Dimming with 25%/12.5%

PWM Dim Signal Input

≤

The MPQ3367 employs a low on-resistor

MOSFET and a low headroom voltage, designed

for higher efficiency. It has a standard I²C digital

interface for ease of use. The switching

frequency can be programmed by a resistor, I²C

interface, or external clock.

I²C Interface

Phase Shift Function for PWM Dimming

2.5% Current Matching

Cycle-by-Cycle Current Limit

Disconnect VOUT from VIN

Optional LED Current Auto-Decrement at

High Temperature

The MPQ3367 provides analog, PWM, and mix

dimming mode with a PWM input. Dimming

mode can be selected with the I²C interface or

the MIX/AD pin. It also has a phase shift function

to eliminate noise during PWM dimming.

•

LED Short/Open, OTP, OCP, Inductor

Short Protection

Robust protections are included to guarantee

safe operation of the device. Protection modes

include over-current protection (OCP), over-

voltage protection (OVP), over-temperature

protection (OTP), LED short, and open

protection. There is also an option that

decreases the LED current automatically at

higher temperatures.

•

Programmable LED Short Threshold

Programmable OVP Threshold

Fault Indicator Signal Output

QFN-24 4mmx4mm and TSSOP28-EP
