Pin Function
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.
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 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.
Output voltage sense pin — output voltage regulation point (connection node of inductor and output
capacitor).
Ground reference and power ground for the SC195.
Switching output — connect an inductor between this pin and the load to filter the pulsed output current.
Input power supply pin — connect a bypass capacitor from this pin to GND.
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.
