DESCRIPTION
The SSR01-SERIES high performance switching regulators are suited to pick and place
mass production. It provides 1A output current and high efficiency up to 95.5%. The
SSR01 series feature output short circuit protection, over-current protection, and
over-temperature protection. The SSR01 series can also be used to converter a positive
voltage into a negative voltage.

The input voltage can be increased to 42VDC by external capacitors.
1.For Positive output:
Input capacitor is necessary when input voltage 36VDC increased to 42VDC. The input capacitor suggestion is 22uF
2.For Negative output application:
The input and output capacitors are necessary for negative output application when the 36VDC be increased to 42VDC, and the suggestion of
capacitors: The C1 is 22uF and the C2 is 10uF. (Please refer to the figure of positive to negative output application)
Consider to the maximum duty of internal controller. In the trim down application, these are some condition that input range can’t increase to 42VDC.
