MPQ4425M High Efficiency 1.5A, 36V, 2.2MHz Synchronous Step-Down LED Driver AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ4425M is a high-frequency, EMI Reduction Technique synchronous, rectified, step-down, switch-mode Wide 4V-to-36V Operating Input Range white LED driver with built-in power MOSFETs. 85m/50m Low R Internal Power DS(ON) It offers a very compact solution to achieve a MOSFETs 1.5A continuous output current with excellent High-Efficiency Synchronous Mode load and line regulation over a wide input Operation supply range. The MPQ4425M has Default 2.2MHz Switching Frequency synchronous mode operation to get high PWM Dimming (Min 100Hz Dimming efficiency. Frequency) Forced CCM Mode Current-mode operation provides fast transient 0.2V Reference Voltage response and eases loop stabilization. Internal Soft-Start Full protection features include over-current Fault Indication for LED Short, Open and protection (OCP) and thermal shut down (TSD). Thermal Shutdown The MPQ4425M requires a minimal number of Over-Current Protection (OCP) with Valley- readily-available standard external components, Current Detection and is available in a space-saving QFN-13 Thermal Shutdown (2.5mmx3mm) package. 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 Automotive LED Lighting All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
