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 CXSU6349 series is a CMOS step-up switching regulator which mainly consists of a reference voltage source, an oscillation circuit, an error amplifier, a phase compensation circuit, a PWM/PFM switching control circuit. With an internal low-ON-resistance Nch Power MOS, this product is applicable to applications requiring high efficiency and high output current. The CXSU6349 series switches its operation to the PFM control circuit whose duty ratio is 15% with to the PWM/PFM switching control circuit under a light load and to prevent decline in the efficiency 二.产品特点 Low voltage operation: Start-up is guaranteed from 0.9 V(IOUT =1 mA ) Duty ratio: Built-in PWM/PFM switching control circuit 15 to 78 % . oscillator frequency：1.0MHz Output voltage range: 1.5V ~6.5 V Output voltage accuracy：±2% Soft start function: 2 mS. 三.应用范围 MP3 players, digital audio players Digital cameras, GPS, wireless transceiver Portable devices 四.技术规格书（产品PDF) 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 五.产品封装图
