MP3308DL-LF-P

LED Driver IC Overview

The MP3308DL-LF-P is a synchronous step-up DC-DC converter designed for white LED driving applications. It integrates a 1.33A power switch and operates from an input voltage range of 2.5V to 5.5V. The device supports adjustable output voltages up to 24V with a fixed switching frequency of 1.2MHz. Key electrical parameters include a quiescent current of 60µA in shutdown mode and a typical efficiency exceeding 90%. It features programmable soft-start, over-current protection, and thermal shutdown. The component is housed in a compact 14-pin QFN package (3mm x 3mm) suitable for space-constrained portable electronics.

LED Driver IC Procurement Notes

Verify the specific suffix 'P' indicates tape-and-reel packaging configuration as per MPS standard nomenclature. Confirm RoHS compliance status through the official datasheet or certificate of conformity. Ensure the ordering part number matches the exact temperature grade and package variant required for your PCB assembly process. Cross-reference with the manufacturer's latest lifecycle notification to confirm availability status.

LED Driver IC Selection Notes

Select this component when designing LED drivers requiring high efficiency within a small form factor. The fixed 1.2MHz frequency allows for the use of small inductors and capacitors, reducing overall board area. Consider the input voltage range compatibility with single-cell lithium-ion batteries. Evaluate the thermal performance requirements based on the expected LED current and ambient operating conditions.
