高效率、低噪声、无电感、降压型 DC/DC 转换器

LTC®3250-1.5 / LTC3250-1.2 是充电泵降压型 DC/DC 转换器，其可采用 2.7V 至 5.5V 输入产生一个 1.5V 或 1.2V 的稳定输出。这些器件采用开关电容器分数转换以实现比线性稳压器高两倍的典型效率。无需电感器。一种独特的恒定频率架构可提供一个低噪声稳定输出以及低于传统充电泵稳压器的输入噪声。高频操作 (fOSC = 1.5MHz) 简化了滤波，以进一步降低传导噪声。另外，该器件还采用了突发模式 (Burst Mode®) 操作以改善轻负载时的效率。低工作电流 (无负载时为 35μA，在停机模式中则 <1μA) 和低外部组件数目 (3 个小的陶瓷电容器) • 2.7V 至 5.5V 输入电压范围\n\n• 无电感器\n\n• 锂离子电池 (3.6V) 至 1.5V 转换具有 81% 的效率\n\n• 低噪声恒定频率操作\n\n• 输出电压：1.5V ±4%，1.2V ±4%\n\n• 输出电流：250mA\n\n• 停机模式把负载与 VIN 断接\n\n• 低工作电流：IQ = 35μA\n\n• 低停机电流：ISD < 1μA\n\n• 振荡频率 = 1.5MHz\n\n• 软启动可限制接通时的浪涌电流\n\n• 短路和过热保护\n\n• 外形扁平 (仅高 1mm) 的 SOT-23 封装;
