Overview
The MP3397ES-LF-Z is a white LED driver IC from Monolithic Power Systems, designed for high-performance lighting applications. It supports up to four LED strings with a maximum current of 350 mA per channel. Operating on a boost topology, the device accepts an input voltage range of 5 V to 28 V and functions at a fixed switching frequency of 540 kHz. The component is housed in a SOIC-16 package and offers PWM dimming capabilities. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Supports up to four independent LED output channels
- Integrates a boost converter topology for efficient power conversion
- Enables precise brightness control via PWM dimming signals
Applications
- General solid-state lighting systems
- Commercial LED illumination fixtures
- Residential LED downlights
Procurement Notes
Verify the specific suffix (LF-Z) against official documentation to confirm lead-free status and reel packaging specifications. Confirm that the NRND status does not impact existing production requirements. Ensure compatibility with the required SOIC-16 footprint and thermal management constraints during integration.
Selection Notes
Select this component when designing circuits requiring multi-string LED drive capability with a wide input voltage range. Consider the fixed 540 kHz switching frequency for EMI filtering requirements. Evaluate the SOIC-16 package size against available board space and thermal dissipation needs for the target application environment.
Part Context
This part belongs to the MP3397 series of LED drivers manufactured by Monolithic Power Systems. It is categorized under LED Lighting Drivers and utilizes a boost topology. The device is distinct from other MPS regulators like the HF500GS or MP9486 series due to its specific focus on multi-channel white LED driving.
Replacement Considerations
Official documentation indicates the MP3394S as a recommended alternative for new designs. Verify electrical parameter compatibility before substitution.
