MPQ2483A

Industrial/Automotive-Grade

55V, 2.5A Programmable

Frequency LED Driver

Available in AEC-Q100

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MPQ2483A is a 55V LED driver suitable for

either step-down or inverting step-up and step-

down applications. It achieves a 2.5A peak

current with excellent load and line regulation

over a wide input supply range.



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

(OCP)

The MPQ2483A incorporates both DC and

PWM dimming into a single control pin. The

separate input reference ground allows for

direct enable and dimming control for positive-

to-negative power conversion.



Thermal Shutdown, Over-Voltage (OVP),

Short–Circuit (SCP), and Open-String

Protection

Current-mode operation provides fast transient

response and eases loop stabilization. Full

protection features include cycle-by-cycle peak

current limiting, output over-voltage protection

(OVP), open-string protection, output short-circuit

protection (SCP), and thermal shutdown.



AEC-Q100 Qualified

APPLICATIONS



General LED Illumination

LCD Backlight Panels

Automotive Lighting

The MPQ2483A requires a minimal number of

readily available, standard, external components

and is available in 10-pin QFN (3mmx3mm) and

14-pin SOIC14 packages.

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

MPS green status, please visit the MPS website under Quality Assurance.
