MP3304BDD-LF-P

LED Driver IC Overview

The MP3304BDD-LF-P is a high-efficiency boost DC-DC regulator designed for white LED driving applications. It operates with an input voltage range of 3 V to 6 V and provides an adjustable output voltage from 3 V to 36 V. The device integrates a 1.33 A switch and supports PWM dimming control. It functions at a fixed switching frequency of 2.2 MHz, enabling the use of small external components. The IC is housed in an 8-pin QFN (2x3 mm) package and is rated for operation between -40°C and +85°C.

LED Driver IC Feature Summary

• Integrates a high-current internal power switch for efficient step-up conversion
• Supports true PWM dimming for precise brightness control without color shift
• Fixed high-frequency operation minimizes passive component size
• Compact surface-mount packaging facilitates dense board layouts

LED Driver IC Applications

• White LED backlighting for portable electronic devices
• High-brightness LED illumination modules
• Battery-powered lighting systems requiring compact drivers

LED Driver IC Procurement Notes

Verify the specific suffix 'LF-P' against the manufacturer's current datasheet to confirm lead-free status and tape-and-reel packaging configuration. Ensure the design accounts for the NRND (Not Recommended for New Designs) status if applicable to long-term supply requirements. Confirm thermal dissipation capabilities within the QFN-8 package for the intended load conditions.

LED Driver IC Selection Notes

Select this component when a single-channel boost driver is required for white LEDs with an input voltage up to 6 V. The 2.2 MHz frequency is suitable for designs prioritizing small inductor size over ultra-low EMI. Verify that the required output voltage does not exceed the 36 V limit and that the LED string current remains within the 1.33 A switch rating.

LED Driver IC Part Context

This part belongs to the MP3304 series of LED drivers from Monolithic Power Systems. It shares functional similarities with variants like the MP3304ADD-LF-Z but differs in package type and specific pinout configurations. The series is characterized by high efficiency and integrated protection features for LED string management.

LED Driver IC Replacement Considerations

The MP3304BDD-LF-Z is a direct equivalent variant differing primarily in packaging quantity or reel specification. Other MP3304 family members may require schematic and layout modifications due to pinout differences.
