Figure 11.
Main switching regulator functional blocks
In pulse skipping control the duty cycle must be chosen by the user depending on supply
voltage and output regulated voltage. Therefore the switching regulator has 4 possible duty
cycles that can be changed by writing the VmainSwSelPWM bits in the MainSwCfg register
according to following Table 10.
The output current is limited to a value that can be set by means of SelIlimit bit in the
MainSwCfg register according to following Table 11.
