Io below this value will not damage these converters, however, they may not meet all listed specifications. 2. Typical value, tested at nominal input and full load. 3. Specifications subject to change without notice. 4. This power module is not internally fused. The input line fuse must always be used. 5. Input Back Ripple Current is tested and specified over a 5 Hz to 20 MHz bandwidth. Input filtering is Cin=2x 100 uF, Cbus=1000 uF, Lbus=1 uH. All caps are low ESR types.

Copper strip DC/DC converter Co Oscilloscope Load Copper strip Co: usually 10uF to 47uF use low-ESR ceramic. 2. Temperature derating curve: The DC-DC converter will operate over a wider temperature range if less power is drawn from the output and the device is already running. The temperature derating curve shows the operating power-temperature range. As shown below.
