MPQ2483

Industrial/Automotive-Grade

55V, 2.5A Programmable

Frequency LED Driver

Avaiable in AEC-Q100

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MPQ2483 is a 55V, LED driver suitable for

either step-down or inverting step-up/down

applications. It achieves 2.5A peak current over

a wide input supply range with excellent load

and line regulation. Current mode operation

provides fast transient response and eases loop

stabilization. Fault condition protection includes

thermal shutdown, cycle-by-cycle peak current

limiting, output over voltage protection, open

strings protection and output short circuit

protection.

•

2.5A Maximum Peak Current

Buck or Buck-Boost Modes

Wide 4.5V to 55V Operating Input Range

0.28Ω Internal Power MOSFET Switch

Analog and PWM Dimming

0.198V Reference Voltage

5μA Shutdown Mode

Stable with Low ESR Capacitors

Cycle-by-Cycle Over Current Protection

Thermal Shutdown, Over Voltage, Short

Circuit & Open String Protection

AEC-Q100 Qualified

The MPQ2483 incorporates both DC and PWM

dimming onto a single control pin. The separate

input reference ground pin allows for direct

enable and/or dimming control for a positive to

negative power conversion.

APPLICATIONS

•

General LED Illumination

LCD Backlight Panels

Automotive Lighting

The MPQ2483 requires a minimum number of

readily available standard external components

and is available in a 10-pin 3mm x 3mm QFN and

SOIC 14-pin packages.

All MPS parts are lead-free, halogen free, and adhere to the RoHS

directive. For MPS green status, please visit MPS website under Quality

Assurance.
