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.
