PT4221 1.8V 输出、5W 48V 输入隔离 DC/DC 转换器
PT4221 描述
The PT4220 power modules are a series of DC/DC converters housed in an ultra-low profile (8mm) solderable copper case. The series includes a number of preset output voltages ranging from 1.3V
up to 12V, all fully approved for Telecom use. They may also be used in many other applications that require input-output isolation over an extended temperature range. The modules are an ideal choice for low-power digital and analog circuits, including DSPs and microcontrollers. The flexibility of input-output isolation also allows the output to be configured for negative voltage operation.
The PT4220 series is made available in both horizontal and vertical pin configurations, including surface mount
