MP3202DG-LF-Z

LED Driver IC Overview

The MP3202DG-LF-Z is a boost converter IC designed to drive up to 39 white LEDs from a single 5V system rail. It operates with an input voltage range of 2.5V to 6V and delivers a maximum output current of 1.3A at a fixed switching frequency of 1.3MHz. The device supports analog and PWM dimming, features a low average feedback voltage of 104mV for high efficiency, and includes protection against overvoltage, overcurrent, and thermal overload. It is housed in an 8-pin QFN (2mm x 2mm) package.

LED Driver IC Feature Summary

• Integrates a power MOSFET and control circuitry for efficient LED driving
• Supports both analog and pulse-width modulation (PWM) dimming methods
• Includes open-load shutdown and internal current limiting protections

LED Driver IC Applications

• Backlight drivers for mobile devices
• Portable electronic display illumination
• General LED lighting applications requiring boost topology

LED Driver IC Procurement Notes

Verify the specific suffix 'DG' corresponds to the QFN-8 package variant when ordering. Confirm RoHS compliance status as indicated by the 'LF-Z' designation. Ensure the selected distributor provides official datasheets matching the Monolithic Power Systems documentation for accurate pinout and electrical characteristics validation prior to integration.

LED Driver IC Selection Notes

Select this component for designs requiring a compact solution to drive multiple series-connected LEDs from a low-voltage source. The fixed 1.3MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 1.3A current limit when sizing inductors and ensuring thermal management within the specified operating temperature range of -40°C to +85°C.

LED Driver IC Part Context

This part belongs to the MP3202 family of LED driver ICs from Monolithic Power Systems. The family includes variants such as MP3202DJ-LF-Z, which utilizes a TSOT-23-6 package. These devices share core functional specifications but differ in physical footprint and pin configuration to accommodate different PCB layout constraints.

LED Driver IC Replacement Considerations

MP3202DJ-LF-Z is a documented alternative within the same product family, offering identical electrical performance in a TSOT-23-6 package instead of QFN-8.
