LTC3526L 采用 2mm x 2mm DFN 封装的 550mA 1MHz 同步升压型 DC/DC 转换器
LTC®3526L / LTC3526LB 是具输出断接功能的同步、固定频率升压型 DC/DC 转换器。同步整流在扁平的 2mm x 2mm DFN 封装中实现了高效率。由于采用了一个 680mV的启动电压，而且一旦起动之后就能够在低至 500mV 的电压条件下运作，因而进一步地延长了采用单 AA / AAA 电池供电型产品的电池使用寿命。
1MHz 的开关频率允许采用纤巧、扁平的电感器和陶瓷电容器，从而最大限度地缩减了解决方案的占板面积。电流模式 PWM 设计采取的是内部补偿，因而减少了外部元件数目。LTC3526L 在轻负载条件下执行突发模式操作，从而使其能够在宽负载范围内保持高效率。而 LTC3526LB 具固定频率操作以满足低噪声应用的要求。抗振铃控制电路通过在断续操作模式中对电感器进行阻尼来降低 EMI。其他的特点包括小于 1μA 的低停机电流和热停机功能。
LTC3526L / LTC3526LB 采用 2mm x 2mm x 0.75mm DFN 封装。
