目录 1.产品概述 2.产品特点 3.应用范围 4.技术规格书下载（PDF文档） 一.产品概述 The CXSU6324 is a steep-up converter designed for driving up to 39 white LEDs(13 strings of 3 LEDs each)from a 5V system rail. The CXSU6324 uses a current mode,fixed frequency architecture to regulate the LED current , which is measured through an external current sense resistor. Its low 101mV feedback voltage reduces power loss and improves sfficiency. The OV pin monitors the output voltage and turns off converter if an over-voltage condition is present due to an open circuit condition. The CXSU6324 includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of output overload. The CXSU6324 is available in small 6-pin Sot23 or 8-pin QFN (2mm*2mm) package. 二.产品特点 ■ 2.5V to 6V Input Voltage Range ■ On Board Power MOSFET ■ Drives up to 39 White LEDs at 5V Input ■ Up to 92% Efficiency ■ Over 1MHz Fixed Switching Frequency ■ Open Load Shutdown ■ Low 104mV Feedback Voltage ■ Soft-Start/PWM Dimming ■ UVLO, Thermal Shutdown ■ Internal 1.3A Current Limit 三.应用范围 ■ Cell Phones ■ Handheld Computers and PDAs ■ Digital Still Cameras ■ Small LCD Displays
