双通道高效率PWM降压型 DC/DC 转换器

RT8020 为双通道高效率脉波宽度调变(PWM)降压型DC/DC 转换器。可在宽输入范围2.5V 至 5.5V输出1A电流。RT8020适用于由单一锂电池供电的可携式电子装置，例如移动电话、PDA与掌上型装置。\n\nRT8020 具备两种操作模式:PWM/低压降 自动切换模式以及关机模式。操作于PWM模式时可藉由内部具备低R_DS(ON)的同步整流组件大幅的降低导通损耗。并不需外加萧特基二极管于实际应用中。\n\nRT8020当PWM操作时无法连续导通上端PMOS时，进入低压降模式。当EN脚位为低电位时，进入关机模式，消耗电流小于0.1μA。\n\n由于操作在固定频率1 • 2.5V 至5.5V 输入范围\n• 1.2V、1.3V、 1.8V、 2.5V 与 3.3V 的固定/可调 输出电压\n• 效率达95% \n• 每通道50μA 的静态电流\n• 小型的 12-引脚 WDFN 封装\n• 符合RoHS规范与100%的引脚无铅特性;
