ME3103
ME3103是电流型直流-直流转换器。在重负载,频PWM控制执行良好的稳定性和瞬态响应。确保电池寿命最长在便携式应用程序中,ME3103提供节电脉冲-Skipping调制(PSM)模式来降低静态电流负载较轻的操作来节约电能。
ME3103支持范围的输入电压2.5 v至2.5 v,允许使用一个单一的李+/Li-polymer细胞,多个碱性/镍氢电池,USB和其他标准的电源。输出电压可调从0.6 v的输入电压,而零件号后缀ME3103显示预先设定的输出电压3.3 v,2.8 v,2.5 v,1.8 v,1.5 v,1.2 v或可调。所有版本使用内部电源开关和同步整流器来减少外部计数,实现效率高。在停工期间,输入与输出和电流小于0.1μa关闭。其他关键特性包括欠压锁定,以防止电池深放电。
效率高达96%
●只有40μa(TYP。)静态电流
●输出电流:1A
●内部同步整流器
●1.5 mhz切换频率
●软启动
●欠压锁定
●短路保护
●热关机
The ME3103 is a step-down current-mode, DC-DC converter. At heavy load, the constant-frequency PWM control performs excellent stability and transient response. To ensure the longest battery life in portable applications, the ME3103 provides a power-saving pulse -Skipping Modulation (PSM) mode to reduce quiescent current under light load operation to save power.
The ME3103 supports a range of input voltages from 2.5V to 5.5V, allowing the use of a single Li+/Li-polymer cell, multiple Alkaline/NiMH cell, USB, and other standard power sources. The output voltage is adjustable from 0.6V to the input voltage, while the part number suffix ME3103 indicates pre-set output voltage of 3.3V, 2.8V, 2.5V, 1.8V, 1.5V, 1.2V or adjustable. All versions employ internal power switch and synchronous rectifier for to minimize external part count and realize high efficiency. During shutdown, the input is disconnected from the output and the shutdown current is less than 0.1μA. Other key features include under-voltage lockout to prevent deep battery discharge.
