SGM3780 - 1.5A Flash LED Driver

General Description

The SGM3780 is the ideal power solution for high-power flash LEDs used with cell phone camera modules or digital still cameras.

It is a highly integrated step-up DC/DC converter with very high switching frequency, fixed at 2MHz, providing a very small total solution for portable photo flash.

Key Features

  • Input Voltage Range: 3V to 5V.
  • Dual Flash LED Outputs.
  • Drive Up to Total 1.5A or 0.75A per Channel.
  • High Efficiency LED Driver (Up to 90%).
  • 2MHz Step-Up Converter.
  • Very Small Inductor: 1.0μH.
  • Independent Flash Mode Enable and Movie/Torch Mode Enable Pins.
  • Flash Mode or Movie/Torch Mode Dimming via PWM Control.
  • 10kHz to 200kHz PWM Dimming Frequency.
  • One Resistor Sets Flash Mode LED Current.
  • One Resistor Sets Movie/Torch Mode LED Current.

SGM3780 2MHz, 1.5A Flash LED Driver in TDFN-3×2-14L Package GENERAL DESCRIPTION The SGM3780 is the ideal power solution for high-power flash LEDs used with cell phone camera modules or digital still cameras. It is a highly integrated step-up DC/DC converter with very high switching frequency, fixed at 2MHz, providing a very small total solution for portable photo flash. The SGM3780 has separate Flash mode and Movie/Torch mode enable pins for maximum flexibility. Flash mode is usually used with 660ms timer control to generate a high intensity flash. The Flash mode and Movie/Torch mode LED current is programmed by external resistors respectively, making the flash LED solution simple to control.
