DC/DC Converter
RTC2
Description
The RTC2 is a 2W, open-frame, SMD, isolated DC/DC converter with 2:1 input voltage range. It is
available with 5V (4.5-9V) or 24V (18-36V) inputs and offers a single 5V output which is short circuit
protected. The output is tightly regulated with less than 50mV output ripple. There is no minimum load
requirement. The operating temperature is -40°C up to 100°C (with derating). Isolation is 3kVDC/1kVAC
(Basic Isolation) and a control pin is fitted as standard. The converter is IEC/EN62368-1 certified and is
10/10 RoHS-conform. Class B EMC conformity can be reached with a simple external LC filter.
