产品介绍





概述 ME2101 系列 DC/DC 芯片是采用 CMOS 工艺制造 的低静态电流的 PWM 开关型 DC/DC 升压转换器。该系 列芯片采用

先进的电路设计和制造工艺,极大地改善了开 关电路固有的噪声问题,减小对周围电路的干扰。输出电 压 为 2.0V~5.0V

( 按 0.1V 的 级 差 ), 振 荡 频 率 为 100KHz(典型值)。对内置开关晶体管的 ME2101AxxX, 组成 DC/DC 升压电路只需

接三个外围元件, 一只肖特基 二极管、一只电感和一只电容。CE 使能端,可关断芯片, 使功耗达到最小。供电电源和电压

检测分离,具有反馈功 能,输出电压可调。该电路内部的软启动电路能够有效限 制电路启动时引起的电流浪涌,提高了芯

片的可靠性。该 系列芯片适用于低噪声、较大电流的电池供电设备。

特点

l 只需少量的外接元件:仅一只肖特基二极管、一只电 感和一只电容

l 低纹波及低噪声

l 工作电压范围:0.9V~6.5V

l 带 载 能 力 强 : 当 Vin=3.0V 且 Vout=3.3V 时 Iout=350mA

l 输出电压范围:2.0V~5.0V(步长 0.1V)

l 输出电压高精度:±2.5%

l 低启动电压:最高值为 0.9V(输出电流为 1mA 时)

l 最大工作频率:100KHz(典型值)

l 高效率:典型值为 87%

l 软启动时间:典型值为 15mS

应用场合

l 电池供电设备的电源部分

l 无线鼠标、无线键盘、照相机、摄象机、VCR、PDA、 手持电话、电动玩具等便携式设备的电源部分

l 要求提供电压比电池所能提供电压高的设备的电源 部分

封装形式

l 3-pin SOT23-3、SOT89-3

l 5-pin SOT23-5、SOT89-5
