MP4050GS-P

Overview

The MP4050GS-P is a single-channel LED lighting driver IC manufactured by Monolithic Power Systems. It operates within an input voltage range of 4.5 V to 4.7 V and delivers a fixed output current of 5 mA. The device functions at a switching frequency of 33 kHz and supports surface-mount installation in an SOIC-8 package. It is rated for power dissipation up to 1 W and maintains operation across a temperature range of -40°C to +125°C. Maximum supply current is specified at 400 uA.

Feature Summary

• Single-channel LED driver architecture
• Fixed 5 mA output current regulation
• Surface-mount SOIC-8 packaging

Applications

• LED lighting driver circuits
• Low-power illumination systems

Procurement Notes

This component carries an NRND status, indicating it is not recommended for new designs. Engineers are advised to consider the MP4050A as the recommended replacement for future projects. Verify availability constraints and long factory production times before procurement planning.

Selection Notes

Select this part only for legacy or existing designs requiring a 4.5 V to 4.7 V input range and 5 mA output. Due to its non-recommended-for-new-designs status, alternative components like the MP4050A should be evaluated for new implementations to ensure long-term supply stability.

Part Context

The MP4050GS-P belongs to the LED Lighting Drivers product category under Monolithic Power Systems. It is classified specifically as a Driver IC designed for low-voltage LED applications. The GS suffix denotes the SOIC-8 package variant with specific thermal and electrical characteristics defined by the manufacturer.

Replacement Considerations

The MP4050A is explicitly recommended by the manufacturer as the replacement for new designs.
