Product details

ADP2108是一款高效、低静态电流的降压型DC-DC转换器，采用超小的5焊球WLCSP封装。整体解决方案仅仅需要三个极小的外部元件。它采用专利的高速电流模式、稳频脉宽调制（PWM）控制机制来提供优异的稳定性和瞬间响应。为了保证在便携应用中实现最高的电池续航能力，ADP2108提供一种节能模式来降低轻负载条件下的开关频率。

ADP2108可工作在2.3V到5.5V的输入电压下，可使用单节锂或者锂聚合体电池、复合碱性或者镍氢电池、PCMCIA、USB及其它标准电源。在上述输入电压范围之内最大负载电流为600mA。

ADP2108可提供3.3V、3.0V、2.5、2.3V、1.8V、1.5、1.3V、1.2V、1.1V及1.0V的固定输出电压。为了实现最少的外部器件数量及高效率，所有版本均内置电源开关和同步整流器。ADP2108内置一个软启动功能并具有内部补偿机制。在逻辑控制关断期间，输入是与输出断开的，输入源漏电流小于0.1A。其它的关键性能包括防止深度电池放电的欠压闭锁以及防止在启动时输入电流过冲的软启动。ADP2108采用5焊球WLCSP封装。
