产品概述 返回TOPIBc嘉泰姆
The CXLE87125 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 CXLE87125 has separate Flash mode and Movie/Torch mode enable pins for maximum flexibility. 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.IBc嘉泰姆

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.IBc嘉泰姆

Various protection features are built into the CXLE87125, 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.IBc嘉泰姆
