1.5A Flash LED Driver

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. If both enable pins are at logic high, the LED current will be programmed by the Movie/Torch mode setting resistor. The two LED output sinks can be shorted together externally for higher power single flash LEDs, up to 1.5A continuous LED current. Thermal regulation is integrated in Flash mode to limit the IC’s temperature and continuously provide the maximum allowed output current. Various protection features are built into the SGM3780, 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. 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 t.
