Pin Function
Regulated output, with respect to VIN, of the front-end LDO. A decoupling capacitor is connected to
this pin. This input goes directly to the internal MOSFET switch.
Input power supply voltage .
Regulated output voltage and feedback for SC190.
Enable (digital input): high input enables the SC190, a low disables and reduces quiescent current to
0.1μA. In shutdown, LX becomes high impedance.
Mode select pin (digital input): MODE = VIN - linear regulator mode; MODE = GND - switcher mode.
Oscillator synchronization input. Tie to VIN for forced continuous mode or external clock for frequency
synchronization.
Logic level Bit 0 used in conjunction with VID1 to set the output voltage.
Logic level Bit 1 used in conjunction with VID0 to set the output voltage.
Ground.
Inductor connection to the switching FETs.
Pad for heatsinking purposes. Not connected internally. Connects to ground plane using multiple
vias.
