MPQ4425A

High Efficiency 1.5A, 36V, 2.2MHz,

Synchronous Step-Down LED Driver,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The

MPQ4425A

high-frequency,



Wide 4V to 36V Operating Input Range

85mΩ/50mΩ Low R_DS(ON)Internal Power

MOSFETs

High-Efficiency Synchronous Mode

Operation

Default 2.2MHz Switching Frequency

PWM Dimming (Min 100Hz Dimming

Frequency)

synchronous, rectified, step-down, switch-mode

white LED driver with built-in power MOSFETs.

It offers a very compact solution to achieve 1.5A

of continuous output current with excellent load

and line regulation over a wide input supply

range. The MPQ4425A has synchronous mode

operation to get high efficiency.



Forced CCM Mode

0.2V Reference Voltage

Internal Soft Start

Fault Indication for LED Short, Open, and

Thermal Shutdown

Over-Current Protection (OCP) with Valley

Current Detection

Thermal Shutdown

CISPR25 Class 5 Compliant

Available in a QFN-13 (2.5mmx3mm)

Package

Current mode operation provides fast transient

response and eases loop stabilization. Full

protection

features

include

over-current

protection (OCP) and thermal shutdown (TSD).

The MPQ4425A requires a minimal number of

readily available, standard external components,

and is available in a space-saving QFN-13

(2.5mmx3mm) package.



Available in a Wettable Flank Package

Available in AEC-Q100 Grade-1

APPLICATIONS



Automotive LED Lighting
