SGM6014是圣邦微推出的高效率同步降压型DC-DC转换器，其输入电压范围为2.5V~5.5V，输出电压最低1.2V，可提供固定电压输出和可调电压输出，其中固定电压输出电压轨包括1.2V、1.8V、3.3V。该款DC-DC的输出电流可达2A，在峰值负载条件下，转换效率可高达95%，可完美适用于采用单节锂电池供电的便携设备的设计。

SGM6014可支持100%占空比，可使最小压差更低，从而可延长电池使用寿命。同时，在低负载情况下，SGM6014输出纹波低，适合对噪声敏感的应用。此外，该款DC-DC的开关频率可达1.4MHz（固定），在保证低开关损耗的条件下，可使外部器件的尺寸更小。此外，SGM6014的导通阻抗仅0.135Ω，可使芯片自身损耗更低，在PFM模式下，其静态工作电流仅55uA，可确保在轻负载时具有高效率，延长电池续航时间。并且，SGM6014的关断电流小于2uA，非常适合低功耗系统的设计。

SGM6014支持软启动保护，可避免上电过冲损坏后端电路，同时内部集成的短路保护电路和过热关断保护电路则可有效防止意外损坏芯片。SGM6014的工作温度范围-40~+85℃，采用TDFN-3×3-10L封装，超小型封装更适合便携产品的设计。
