Pin Function
Input power supply voltage; this input goes directly to the internal MOSFET switches.
Bypass capacitor pin; an external capacitor combined with an internal resistor provides a
filtered supply voltage for the internal control circuitry. Connect a 0.1uF capacitor from BP to
ground.
Analog ground.
Compensation pin for the error amplifier.
Output adjust pin; connect to a resistor divider to set the output voltage.
Digital current limit select input. Connect ILIM to GN D for 0.6A current; connect ILIM to VIN for
1.2A current limit.
Oscillator synchronization input. Tie to VIN for forced PWM mode, GN D to enable power save
mode, or an external clock signal for frequency synchronization.
Enable digital input; a high input enables the SC192 a low disables the device and reduces
quiescent current to 0.1uA. In shutdown, LX becomes high impedance.
Inductor connection to the switching FETs.
Power Ground.
Pad for heatsinking purposes. Connect to ground plane using multiple vias. N ot connected
internally.
