0.85V启动，500mA PWM同步升压转换器

ETA1019是一款0.85V启动的PWM控制同步升压转换器。ETA1019一般可满足500mA的输出电流，最高输出电压为5V。在空载待机时，功耗在100uA左右。同时ETA1019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·0.5A输出电流\n·高达95%的转换效率\n·1MHz开关频率\n·PWM控制方式 空载待机电流100uA\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;
