Pin Function
Switching node sense pin — for test purposes only.
Output sense pin — connect to output capacitor for proper sensing of output voltage.
Control bit 3 — see Table 1, page 2, for decoding. This pin has a weak pull-down resistor (> 1MΩ) in place at
reset that is removed when CTL3 is pulled above the logic high threshold.
Control bit 0 — see Table 1, page 2, for decoding. This pin has a weak pull-down resistor (> 1MΩ) in place at
reset that is removed when CTL0 is pulled above the logic high threshold.
Control bit 1 — see Table 1, page 2, for decoding. This pin has a weak pull-down resistor (> 1MΩ) in place at
reset that is removed when CTL1 is pulled above the logic high threshold.
Control bit 2 — see Table 1, page 2, for decoding. This pin has a weak pull-down resistor (> 1MΩ) in place at
reset that is removed when CTL2 is pulled above the logic high threshold.
Input power supply pin — connect a bypass capacitor from this pin to GND.
Ground reference and power ground for the SC202.
Regulator output pin — connect a 10μF ceramic capacitor to this pin for proper filtering.
