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.

Notes:

Note1: Efficiency is tested at nominal input and full load at +25°C ambient.

Note2: Max. cap. load is tested at minimum input and full resistive load.

Notes:

Note3: without suffix, standard tray packaging

add suffix „-R“ for Tape and Reel packaging
