特性描述

定电压 1W 系列产品是专门针对线路板上分布式电源系统应用而设计的，主打隔离变压功能。适用于输入电源的电压比较稳定，输入与输出要求隔离，对电压稳定度要求不高的场合。

整个产品序列分稳压型和非稳压型。稳压（既 I 字母开头的）是非稳压的进阶型号，优化了输出纹波噪声指标。

基于产品特性，该系列产品适用于：纯数字电路、一般低频模拟电路、继电器驱动电路、数据交换电路、RS485/232 芯片供电等。

常见问题

什么是定电压电源模块？

定电压电源模块是指输入电压范围最大只允许 ±10% 变化的电压转换器，如果是带稳压输出的型号更缩小到 ±5% 范围。定电压模块电路结构相对简单，不具备过多的保护特性，主打成本低廉组合灵活。

定压模块既然输入电压范围这么窄，那适应性一定很差吧？

恰恰相反，定压模块适用性相当广泛。通常来说，在电路结构中前端一般会配备标准开关电源或者大功率DC-DC模块，其输出电压是稳定可靠的。在后级不同的子电路中，微小功率的定电压模块灵活性就体现出来了，其自由组合、分布式供电的优点展现无余。
