在PTH12050系列的输出电压调整
超宽输出电压调整范围提供了重要的优势，为用户谁
select the PTH12050. It is no longer necessary to purchase a variety of modules
为了覆盖不同的输出电压。输出电压可以修剪
in a range of 1.2 Vdc to 5.5 Vdc for suffix ‘W’ and 0.8 Vdc to 1.8 Vdc for suffix ‘L’.
When the PTH12050 converter leaves the factory the output has been adjusted to
the default voltage of 1.2 V for the PTH12050W and 0.8 V for the PTH12050L.

A 100 F electrolytic input capacitor is required for proper operation. The
capacitor must be rated for a minimum of 750 mA rms of ripple current. C2 =
10 F ceramic capacitor, required for output voltages of 3.3 V and higher
An external output capacitor is not required for basic operation. Adding 100
在负载分布电容μF将改善瞬态响应。
