Notes:  
1. When the SWCTRL pin is HIGH or left open, the switch-mode regulator output will be preset at 3.5V using internal precision  
resistors. When the SWCTRL pin is LOW, the output voltage may be programmed with external resistors. Please refer to  
the Applications Section for output voltage selection information.  
2. Setpoint accuracy is the initial output voltage variability under the specified conditions. When SWCTRL is LOW, the matching  
of the external resistors will have a major influence on this parameter.  
3. Cumulative DC accuracy includes setpoint accuracy, temperature drift, line and load regulation, and output ripple.  
4. The on-time pulse width of the oscillator is preset using external capacitor C . See Typical Operating Characteristics
