MPQ4425A High Efficiency 1.5A, 36V, 2.2MHz, Synchronous Step-Down LED Driver, AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ4425A is a high-frequency, Wide 4V to 36V Operating Input Range synchronous, rectified, step-down, switch-mode 85m/50m Low R Internal Power DS(ON) white LED driver with built-in power MOSFETs. MOSFETs It offers a very compact solution to achieve 1.5A High-Efficiency Synchronous Mode of continuous output current with excellent load Operation and line regulation over a wide input supply Default 2.2MHz Switching Frequency range. The MPQ4425A has synchronous mode PWM Dimming (Min 100Hz Dimming operation to get high efficiency. Frequency) Forced CCM Mode Current mode operation provides fast transient 0.2V Reference Voltage response and eases loop stabilization. Full Internal Soft Start protection features include over-current protection (OCP) and thermal shutdown (TSD). Fault Indication for LED Short, Open, and Thermal Shutdown The MPQ4425A 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. CISPR25 Class 5 Compliant Available in a QFN-13 (2.5mmx3mm) Package 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.
