L5200L-AD-SM1-T 数据手册
UNISONIC TECHNOLOGIES CO., LTD L5200 LOW NOISE, REGULATED CHARGE PUMP DC/DC CONVERTERS 6 5 CMOS IC MSOP-8 4 DESCRIPTION The UTC L5200-xx series are low noise, constant frequency charge pump DC/DC converters and designed to increase efficiency in white LED application. The operating voltage range is 2.7V ~ VOUT input with up to 100mA of output current. Low external parts counts (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the UTC L5200-xx series ideally suited for small, battery-powered applications. A charge-pump architecture maintains constant switching frequency to zero load and reduces both output and input ripple. The UTC L5200-xx series have thermal shutdown capability to escape the device damaged from a continuous short-circuit. With built-in soft-start circuitry to prevents excessive current flow at VIN during start-up. High switching frequency enables the use of small ceramic capacitors. A low-current shutdown feature disconnects the load from VIN and reduces quiescent current to

1. 物料型号: - L5200-ADJ:可调版本,采用MSOP-8封装。 - L5200-xx:固定版本,提供SOT-26和TSOT-26封装。 - Pb-free plating product number: L5200L。

2. 器件简介: - UTC L5200-xx系列是低噪声、恒定频率的电荷泵DC/DC转换器,旨在提高白光LED应用的效率。工作电压范围是2.7V至Vout,输出电流高达100mA。外部零件数量少(一个悬浮电容和两个在VIN和VOUT的小旁路电容),适合小型、电池供电的应用。

3. 引脚分配: - L5200-ADJ (MSOP-8): - 1脚:C+(悬浮电容正极) - 2脚:VIN(输入供电电压) - 3脚:C(悬浮电容负极) - 4,5脚:GND(地端) - 6脚:SHDN(关闭模式,低电平有效) - 7脚:FB(反馈输入引脚,用于可调输出) - 8脚:Vout(调节后的输出电压) - L5200-xx (SOT-26/TSOT-26): - 1脚:Vout - 2脚:GND - 3脚:SHDN - 4脚:VIN - 5脚:C+ - 6脚:C-

4. 参数特性: - 低噪声恒定频率操作 - 输出电流:100mA - 2MHz开关频率 - 固定输出电压:4.5V/5.0V - 输入电压范围:2.7V至Vout - 自动软启动 - 无需电感器 - 关闭电流小于1µA

5. 功能详解: - 电荷泵架构保持恒定的开关频率,减少输出和输入纹波。 - 具有热关断能力,防止设备因连续短路而损坏。 - 内置软启动电路,防止启动时输入电流过大。 - 高开关频率允许使用小陶瓷电容。 - 低电流关闭功能,断开负载与VIN的连接,将静态电流降至小于1µA。

6. 应用信息: - 适用于需要调节输出电压至2.7V至Vout的应用,如LED驱动器和USB端口至5V电源供应。

7. 封装信息: - L5200-AD-SM1-R和L5200L-AD-SM1-R:MSOP-8封装,胶带卷装。 - L5200-AD-SM1-T和L5200L-AD-SM1-T:MSOP-8封装,管装。 - L5200-xx-AG6-R和L5200L-xx-AG6-R:SOT-26封装,胶带卷装。 - L5200-xx-AH6-R和L5200L-xx-AH6-R:TSOT-26封装,胶带卷装。
