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 a

1.5A continuous output current with excellent

load and line regulation over a wide input



supply

range.

The

MPQ4425M

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

Current-mode operation provides fast transient

response and eases loop stabilization.

Full protection features include over-current

protection (OCP) and thermal shut down (TSD).

The MPQ4425M requires a minimal number of

readily-available standard external components,

and is available in a space-saving QFN-13

(2.5mmx3mm) package.



Over-Current Protection (OCP) with Valley-

Current Detection

Thermal Shutdown

Available in a QFN-13 (2.5mmx3mm)

Package



CISPR25 Class 5 Compliant

Available in a Wettable Flank Package

Available in AEC-Q100 Grade-1

APPLICATIONS
