LED Driver IC datasheet and documents for MC34844AEP

MC34844AEP

LED Driver IC Overview

The MC34844AEP is a high-efficiency SMARTMOS LED driver designed for LCD backlighting in displays ranging from 10 to 27 inches. It operates from supply voltages between 7 V and 28 V. The device integrates a boost DC-DC converter with ten independent constant-current channels, each capable of delivering up to 80 mA. It supports analog and PWM dimming control methods. The component is housed in a 32-pin QFN-EP (5x5 mm) package.

LED Driver IC Feature Summary

Integrates a high-efficiency boost DC-DC regulator with ten independent constant-current output channels
Supports both analog and pulse-width modulation (PWM) dimming control interfaces
Utilizes SMARTMOS technology for optimized power management and thermal performance

LED Driver IC Applications

Backlighting for LCD displays sized 10 to 27 inches
High-efficiency LED driving in portable electronic devices
Industrial display systems requiring multi-channel current regulation

LED Driver IC Procurement Notes

Verify the specific suffix 'AEP' corresponds to the 32-QFN-EP package and tape-and-reel or tray configuration as defined by NXP Semiconductors. Confirm RoHS compliance status through official documentation. Ensure the ordering part number matches the exact electrical specifications required for your design, as variations may exist within the MC34844 family.

LED Driver IC Selection Notes

Select this component when designing for LCD backlights requiring ten independent channels with integrated boost conversion. It is suitable for applications operating within a 7 V to 28 V input range. Consider the 80 mA per channel limit and the 5x5 mm package footprint during PCB layout. Verify compatibility with system dimming requirements for analog or PWM signals.
