Overview
The MP3394SGS-P is a four-channel boost white LED driver IC designed for monitor and TV backlight applications. It operates within an input voltage range of 5 V to 28 V and delivers up to 200 mA per channel. The device utilizes a fixed-frequency current control architecture with an adjustable switching frequency between 140 kHz and 670 kHz. Packaged in a 16-lead SOIC, it supports PWM dimming and includes protections for open LEDs, overvoltage, overtemperature, and undervoltage lockout.
Feature Summary
- Integrates four independent high-side current sources for precise LED string regulation
- Supports flexible system expansion through cascading capability using a single power supply
- Provides comprehensive protection mechanisms including open LED detection and thermal shutdown
Applications
- Backlight drivers for 2D LCD monitors
- Backlight drivers for 3D LCD monitors
- Television display systems
Procurement Notes
Verify the specific suffix against official Monolithic Power Systems documentation to confirm package type and temperature rating. Ensure compatibility with required PCB footprint dimensions. Confirm availability status as product lifecycles may change. Validate that the selected variant meets all environmental compliance requirements for the target application.
Selection Notes
Select this component when designing systems requiring four independent LED channels with integrated boost conversion. Consider the adjustable frequency range to optimize external inductor size and efficiency. Evaluate the 200 mA output limit against total backlight current requirements. Ensure the operating temperature range aligns with the intended deployment environment.
Part Context
This part belongs to the MP3394 series of WLED controllers from Monolithic Power Systems. The series focuses on driving white LED arrays in display backlights. Variants within the family share core functionality but differ in packaging options such as TSSOP or SOIC and specific electrical characteristics defined by manufacturer datasheets.
Replacement Considerations
Official documentation recommends the MP3394S series for new designs. Verify pinout compatibility and electrical specifications before substituting other MPS models or competitor devices.
