MP7200

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

Synchronous LED Driver

DESCRIPTION

FEATURES

The MP7200 is a high-frequency, constant-

current, buck-boost LED driver with integrated

power MOSFETs. It offers a very compact

solution to achieve up to 1.2A of continuous

output current, with excellent load and line

regulation across a wide input supply range. The

MP7200 can also be configured to buck mode to

provide up to 3A of constant load current.



Wide 6V to 42V Operating Input Range

44mΩ/40mΩ Low R_DS(ON)Internal Power

MOSFETs

High-Efficiency Synchronous Mode

Operation

Configurable 1.2A Buck-Boost or 3A Buck

Mode

Configurable LED Current without Current-

Sense Resistor

Default 2.3MHz Switching Frequency for

Buck Mode and 1.15MHz Switching

Frequency for Buck-Boost Mode with

Spread Spectrum

PWM Dimming (Dimming Frequency from

100Hz to 2kHz)

Internal 500Hz Two-Step Dimming with

Configurable Duty Cycle

Fault Indication for LED Short (to GND and

Battery) and Open, Output Over-Voltage,

and Thermal Shutdown



Constant frequency hysteretic control mode

provides extremely fast transient response

without loop compensation. The switching

frequency goes up to a fixed 2.3MHz in buck

mode to reduce the current ripple and improve

EMI, and down to 1.15MHz in buck-boost mode

to optimize efficiency and thermal performance.



Full protection features include over-current

protection (OCP), output over-voltage (OV) and

under-voltage (UV), thermal derating (TD), and

thermal shutdown (TSD). The fault indicator

outputs an active logic low signal if a fault

condition occurs.



Over-Current Protection (OCP) with Latch-

Off Mode

Configurable Thermal Derating via NTC

Remote Temperature Sense

EMI Reduction Technique

The MP7200 requires a minimal number of

readily available, standard external components,

and is available in a space-saving QFN-19

(3mmx4mm) package.



Available in a QFN-19 (3mmx4mm)

Package with Wettable Flanks

APPLICATIONS

 Turn Indicator Lights

 Daytime Running Lights (DRLs)

 Fog Lights

 Rear Lights
