Procurement Notes

Verify the exact suffix against official MPS documentation to confirm packaging and temperature grade specifications. Ensure compatibility with the target application's voltage and current requirements before procurement. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and availability status.

Selection Notes

Select this component for applications requiring a single-channel LED driver with up to 1.5 A output current. The 2.2 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 4 V to 36 V input range for automotive or industrial power supply environments. Verify that the QFN-13 package fits the PCB layout constraints.

Part Context

This part belongs to the MPS LED Lighting Drivers category. It is a monolithic integrated circuit designed specifically for driving LEDs from higher voltage sources. The device integrates high-side and low-side power switches into a single solution, reducing the need for external MOSFETs and simplifying the design process for constant current LED applications.
