PRODUCTION DATA
This S-CONF pin configures the device based on the resistor value. This pin is read after EN/SYNC goes high. The device configuration cannot be changed during operation. The S-CONF value is re-read if EN is pulled below 200 mV or if VIN falls below UVLO. Table 7-1 shows the configuration options of the following:
S-CONF | SWITCHING FREQUENCY | SPREAD SPECTRUM | OUTPUT DISCHARGE | SYNCHRONIZATION |
---|---|---|---|---|
VIN | 2.2 MHz | OFF | OFF | No |
GND | 1 MHz | OFF | OFF | No |
4.87 kΩ | 2.2 MHz | OFF | OFF | 1.9 MHz to 2.42 MHz |
6.04kΩ | 2.2MHz | Triangle | OFF | No |
7.5 kΩ | 2.2 MHz | Random | OFF | No |
9.31 kΩ | 1 MHz | OFF | OFF | 0.9 MHz to 1.2 MHz |
