connected to system ground so that ground loops are avoided. See Applications Discussion
for details.
External capacitor.
A 180pF capacitor is connected to this pin as part of the constant
on-time pulse width circuit. Careful layout of this pin is critical to system performance.
See Applications Discussion for details.
Switching regulator control input.
Accepts TTL/open collector input levels. A logic level
HIGH on this pin presets the switching regulator output voltage at 3.5V using internal
resistors. A logic level LOW on this pin will select the output voltage set by two external
resistors and the voltage feedback control pin 5 (VFBSW). See Applications Discussion for
details.
All low power internal circuitry returns to this pin. This pin should be
