MP3301GJ-P

LED Driver IC Overview

The MP3301GJ-P is a boost DC-DC converter designed for driving white LED arrays from a single lithium-ion battery. It operates with an input voltage range of 2.5 V to 6 V and supports output voltages up to 36 V. The device regulates a constant output current of 700 mA using a fixed 1.3 MHz switching frequency. It features a low average feedback voltage of 200 mV to minimize power loss. The component includes internal protection mechanisms such as overvoltage shutdown, undervoltage lockout, and thermal overload protection.

LED Driver IC Feature Summary

• Integrates an internal power MOSFET capable of driving up to ten series-connected white LEDs
• Supports both PWM and analog dimming methods for brightness control
• Includes open-load detection that triggers automatic shutdown upon detecting excessive voltage

LED Driver IC Applications

• White LED backlighting in mobile devices
• Portable electronic display illumination
• Single-cell battery powered lighting systems

LED Driver IC Procurement Notes

Verify the specific suffix 'P' indicates the reel packaging configuration when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the TSOT-23-5 footprint matches the target PCB layout requirements exactly.

LED Driver IC Selection Notes

Select this component for applications requiring high efficiency in space-constrained designs. The fixed 1.3 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 700 mA current limit when sizing the LED string length and thermal management strategy.
