MOSFETs

High-Efficiency Synchronous Mode

Operation

Default 400kHz Switching Frequency

PWM Dimming (Min 100Hz Dimming

Frequency)

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 QFN-13 (2.5mmx3mm) and

TSOT23-8 Packages

synchronous, rectified, step-down, switch-mode

white LED driver with built-in power MOSFETs.

It offers a compact solution to achieve a 1.5A of

continuous output current with excellent load and

line regulation over a wide input supply range.

Synchronous mode operation ensures high

efficiency, while current mode operation

provides fast transient responses and eases

loop stabilization. Additional features include

over-current protection (OCP) and thermal

shutdown (TSD).



This device requires a minimal number of readily

available, external components, and is available

in space-saving QFN-13 (2.5mmx3mm) and

TSOT23-8 packages.



Available in AEC-Q100 Grade 1

APPLICATIONS



Automotive LED Lighting

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