MPQ7200A

42V, 1.2A Buck-Boost or 3A Buck,

410kHz with FSS, Synchronous LED Driver,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ7200A is a fixed-frequency, constant

current buck-boost LED driver with integrated

power MOSFETs. It offers a very compact

solution to achieve 1.2A of continuous output

current (I_OUT), with excellent load and line

regulation across a wide input supply range. The

MPQ7200A can also be configured for buck

mode to provide up to 3A of continuous load

current.

•

Built for a Wide Range of Automotive

LED Applications:

o Wide 6V to 42V Operating Input Range

o PWM Dimming (Dimming Frequency

from 100Hz to 2kHz)

o Internal 500Hz Two-Step Dimming with

Configurable Duty Cycle

o Available in AEC-Q100 Grade 1

High Performance for Improved

Thermals:

o Configurable LED Current without

Sensing Resistor

o 44mΩ/40mΩ Low R_DS(ON)Internal Power

MOSFETs

o High-Efficiency Synchronous Mode

Optimized for EMC/EMI:

o Default 410kHz Switching Frequency

(f_SW) with Spread Spectrum

o EMI Reduction Technique

Full Protection Features:

o LED Short (to GND and Battery), LED

Open, and Output OVP with Fault

Indication

o OCP with Latch-Off Mode

o Configurable Thermal Derating

o Thermal Shutdown

•

Constant frequency hysteretic control mode

provides extremely fast transient response

without loop compensation.

Full protection features include over-current

protection (OCP), output over-voltage protection

(OVP) and under-voltage protection (UVP),

thermal derating (TD), and thermal shutdown

(TSD). The fault indicator outputs an active logic

low signal if a fault condition occurs.

•

The MPQ7200A requires a minimal number of

readily available, standard external components,

and is available in a space-saving QFN-19

(3mmx4mm) package.

•

Fast Control Loop:

o Band-Band Control

Additional Features:

o Configurable 1.2A in Buck-Boost Mode

or 3A in Buck Mode

o 5% LED Current Accuracy from 700mA

to 1.2A for Buck-Boost or 1A to 2A for

Buck

o Available in a QFN-19 (3mmx4mm)

Package with Wettable Flank

APPLICATIONS

• Turn Indicator Lights

• Daytime Running Lights (DRLs)

• Fog Lights

• Rear Lights
