SGM3785 - 1.5A Flash LED Driver

General Description

The SGM3785 is the ideal power solution for highpower 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

  • are built into the SGM3785, including cycle-by-cycle input current limit protection, output over-voltage protection, LED fault (open or short) protection and thermal shutdown protection. The leakage current in shutdown is less than 1μA. The SGM3785 is available in a Green TDFN-3×2-14L package. It operates over an ambient temperature range of -40℃ to +85℃.

SGM3785 2MHz, 1.5A Flash LED Driver in TDFN-3×2-14L Package GENERAL DESCRIPTION The SGM3785 is the ideal power solution for highpower 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 SGM3785 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 maxim LED current is programmed by external resistors respectively, making the flash LED solution simple to control.
