目录产品概述 返回TOP The CXSU63012 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 CXSU63012 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 by IC operation current.产品特点 返回TOP 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 ~12 V Output voltage accuracy:±2% Soft start function: 2 mS. PACKAGE:SOT23-5,SOT89-5,SOP8 应用范围 返回TOP MP3 players, digital audio players Digital cameras, GPS, wireless transceiver Portable devices 技术规格书(产品PDF) 返回TOP 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!
