Pin Function
Input power supply voltage
MODE select pin - MODE = V
cycle capability.
Oscillator synchronization input - Tie to V
mode at light loads. Apply an external clock signal for frequency synchronization.
Enable digital input - a high input enables the SC196A; a low disables and reduces quiescent current to
less than 1μA. In shutdown, LX becomes high impedance.
Regulated output voltage and feedback for SC196A
Logic level bit 0 used in conjunction with VID1 to set the output voltage. Connect high or low as required
to select the desired output voltage. If not connected, the output voltage will be indeterminate.
