MP3202DG-LF-P

LED Driver IC Overview

The MP3202DG-LF-P is a monolithic boost converter designed for driving white LEDs, manufactured by Monolithic Power Systems. It operates within an input voltage range of 2.5 V to 6 V and delivers a maximum output current of 1.3 A. The device features a fixed switching frequency of 1.3 MHz and supports a maximum output voltage of 25 V. Encased in an 8-pin QFN package measuring 2 mm x 2 mm, it functions across a temperature range of -40°C to +85°C. Key electrical characteristics include a low average feedback voltage of 104 mV and a maximum supply current of 750 µA.

LED Driver IC Feature Summary

• Integrates a power MOSFET and control circuitry for efficient LED driving
• Supports PWM dimming for brightness control
• Includes open LED protection that shuts down the converter during overvoltage conditions
• Provides comprehensive protection against undervoltage lockout, overcurrent, and thermal overload

LED Driver IC Applications

• Driving up to 39 white LEDs via a 5 V system power rail
• Portable electronic devices requiring compact backlight solutions
• General-purpose LED lighting applications utilizing boost topology

LED Driver IC Procurement Notes

Verify the specific package type and suffix when ordering, as the MP3202 series includes variants with different packaging such as TSOT-23-6 or QFN-8. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

LED Driver IC Selection Notes

Select this component for designs requiring a single-channel boost driver with integrated power switches. The 1.3 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 104 mV feedback voltage for optimizing efficiency in low-voltage systems. Verify that the load requirements do not exceed the 1.3 A current limit or the 25 V output voltage ceiling.

LED Driver IC Part Context

This part belongs to the MP3202 family of white LED drivers from Monolithic Power Systems. The family includes variants like the MP3202DJ-LF-P, which shares similar electrical performance but utilizes a TSOT-23-6 package instead of the QFN-8 form factor found in the DG suffix. These devices are engineered for high-efficiency conversion in space-constrained portable electronics.

LED Driver IC Replacement Considerations

The MP3202DJ-LF-P serves as a functional substitute within the same series, offering identical electrical characteristics but housed in a TSOT-23-6 package. Designers must account for pinout and footprint differences when swapping between the DG and DJ suffixes.
