In the U2 design, jumper J18 can be used to select between the current limit, soft-start time, and internal compensation options shown in Table 2-3. If the desired option is not available, change one of the resistors to the value which sets the desired option.
In the U1 design, change the MODE resistor to the value which sets the desired option.
JUMPER SETTING | MODE RESISTOR | CURRENT LIMIT | SOFT-START TIME | RAMP |
---|---|---|---|---|
1 to 2 pin shorted | 2.21 kΩ | High | 1 ms | 1 pF |
3 to 4 pin shorted(1) | 4.87 kΩ | High | 1 ms | 2 pF |
5 to 6 pin shorted | 11.3 kΩ | High | 1 ms | 4 pF |
7 to 8 pin shorted | 60.4 kΩ | Low | 1 ms | 2 pF |
