MC34848EP

LED Driver IC Overview

The MC34848EP is an LED driver IC and DC-DC controller designed for step-up (boost) topology applications. It features eight independent outputs capable of delivering 80mA or 160mA per channel, with a maximum output voltage of 45V. The device supports PWM dimming control and operates within a switching frequency range of 200kHz to 1.2MHz. It requires a supply voltage between 6V and 14V. Packaged in a 48-QFN-EP (7x7mm) surface-mount case with an exposed pad, it is rated for operating temperatures from -40°C to 85°C.

LED Driver IC Procurement Notes

Verify the part status carefully, as this component is listed as obsolete by the manufacturer. Confirm that the specific suffix 'EP' matches the required 48-QFN-EP package variant. Ensure compatibility with existing PCB footprints and thermal management designs before procurement. Check for available replacement alternatives if long-term supply stability is required.

LED Driver IC Selection Notes

Select this component when designing circuits requiring multiple independent LED channels driven by a single boost controller. It is suitable for applications needing precise current regulation up to 160mA per channel. Consider the 48-pin QFN package constraints for layout and thermal design. Verify that the input voltage range of 6V to 14V aligns with the system power supply.
