Pin Function
Input supply voltage connection to switching FETs — connect the input capacitor between this
pin and PGND directly.
Input supply voltage for control circuits
Oscillator synchronization input. Tie to V IN for forced PWM mode or GND to allow the part to
enter PSAVE mode at light loads. Apply an external clock signal for frequency synchronization.
Enable digital input; a high input enables the SC196, a low disables and reduces quiescent cur-
rent to less than 1 μ A. In shutdown, LX becomes high impedance.
Regulated output voltage sense pin — connect to the output capacitor allowing sensing of the
output voltage.
Output Voltage Adjust and feedback compensation pin - connect resistor divider between this
pin and GND to set the desired output voltage level.
MODE select pin — MODE = V IN to select 100% duty cycle function, MODE = GND to disable
this function.
Ground
Power Ground
Inductor connection to the switching FETs
Pad for heatsinking purposes — not connected internally. Connects to ground plane using
multiple vias.
