MP3394ES-LF-P

Overview

The MP3394ES-LF-P is a Monolithic Power Systems LED lighting driver IC featuring a boost topology with four output channels. It operates within an input voltage range of 5 V to 28 V and supports a maximum output current of 200 mA per channel. The device functions at a switching frequency between 145 kHz and 600 kHz. It is housed in a SOIC-16 package and is rated for operation from -20 °C to +125 °C.

Feature Summary

• Four-channel WLED driver with internal current sources for precise string matching
• Supports cascading multiple units under a single power supply
• Features PWM or DC input burst PWM dimming capabilities
• Includes protection mechanisms for LED open/short circuits, overvoltage, UVLO, and overtemperature

Applications

• Large LCD panel backlighting
• WLED array driving
• Monitor and TV backlight systems

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND) before implementation. Confirm that the specific suffix LF indicates lead-free compliance. Ensure the SOIC-16 package dimensions match the target PCB footprint. Validate that the operating temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component for applications requiring four independent LED strings driven by a single boost converter. Consider its cascading capability if more than four channels are needed without additional power supplies. Verify that the 200 mA per channel limit aligns with the LED specifications. Check compatibility with the desired switching frequency setting resistor.

Part Context

This part belongs to the MP3394 series of LED lighting drivers designed for white LED applications. It utilizes a current control mode and fixed-frequency architecture. The series includes variants with different packages such as TSSOP-16EP and SOIC-16. It is engineered to reduce power consumption through low average feedback voltage.

Replacement Considerations

Public documentation recommends the MP3394S for new designs. Other available variants in the family include MP3394EF-LF-P and MP3394EY-LF-P.
