0.85V启动，300mA 超低功耗PWM同步升压转换器

ETA1017是一款0.85V启动的，超低功耗的PWM控制同步升压转换器。ETA1017一般可满足300mA的输出电流，最高输出电压为5V。在空载待机时，仅耗电10-20uA。同时ETA1017是一款轻载高效的PWM控制升压转换器，不同于简单的PFM升压，没有PFM升压所必须的输出电容必须要有ESR来稳定环路的要求，可使用体积超小的陶片电容。加之其1M开关频率，可采用超小的电感以及本身SOT23-5的小体积封装，特别适合PCB空间有限的手持设备。 · 0.85V启动\n·0.3A输出电流\n·高达92%的转换效率\n·1MHz开关频率\n·PWM控制方式 空载待机电流<20uA\n·可使用MLCC输出电容\n·0.6V反馈电压\n·3.3V/5.0V固定电压选择;
