Output Voltage Configuration
Two registers control the error amplifier reference
voltage. The reference is coarsely set in 15 mV steps
and then finely adjusted in 0.82 mV steps above the
coarse setting (see Registers 6-10 and 6-11). Higher
output voltages can be achieved by using a voltage
divider connected between the output and the +VSEN
pin. Care must be taken to ensure maximum voltage
rating compliance on all pins.
Note:
The OVFCON<VOUTEN> bit must be set
to enable the output voltage setting
registers.
