MP3301GJ - Fixed-Frequency Step-Up Driver

Download the MP3301GJ datasheet PDF. This datasheet also covers the MP3301 variant, as both devices belong to the same fixed-frequency step-up driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP3301 is a step-up converter designed to drive WLEDS arrays from a single-cell, lithium-ion battery.

The MP3301 uses a current-mode, fixedfrequency architecture to regulate the LED current, which is measured through an external current sense resistor.

Key Features

  • Internal Power MOSFET.
  • Drives up to 10 White LEDs in Series.
  • Up to 89% Efficiency.
  • PWM and Analog Dimming.
  • 1.3MHz Fixed Switching Frequency.
  • Low 200mV Feedback Voltage.
  • Internal 700mA Current Limit.
  • Open-Load Shutdown.
  • UVLO, Thermal Shutdown.
  • Available in TSOT23-5 Packages.

MP3301 1.3MHz, 700mA, Fixed-Frequency Step-Up Driver for up to 10 White LEDS DESCRIPTION The MP3301 is a step-up converter designed to drive WLEDS arrays from a single-cell, lithium-ion battery. The MP3301 uses a current-mode, fixedfrequency architecture to regulate the LED current, which is measured through an external current sense resistor. Its low 200mV feedback voltage reduces power loss and improves efficiency. The MP3301 turns off in the presence of an open-circuit over-voltage condition. The MP3301 includes under-voltage lockout, current limiting, and thermal-overload protection to prevent damage in the event of an output overload. The MP3301 is available in a small 5-pin TSOT23 package.
