高效率1.2MHz 2A升压转换器

SDB628是一款固定频率，SOT23-6封装的电流模式升压变换器，高达1.2MHz的工作频率使得外围电感电容可以选择更小的规格。内置软启动功能减小了启动冲击电流。SDB628轻载时自动切换至PFM模式。SDB628包含了输入欠压锁定，电流限制以及过热保护功能。小尺寸的封装给PCB省下更多的空间。 ● 1.2MHZ固定开关频率\r\n\r\n● 内部集成软启动\r\n\r\n● 支持低至1.6V输入电压范围\r\n\r\n● 3.3V入5V出,可以输出800mA\r\n\r\n● 3V入3.3V出,可以输出800mA\r\n\r\n● 超小型SOT23-6封装;
