Mode-of-operation selection
Figure 39. VSEL and NOSKIP multifunction pin configurations
The PM6675S has been designed to satisfy the widest range of applications. The device is
provided with some multilevel pins which allow the user to choose the appropriate
configuration. The VSEL pin is used to firstly decide between fixed preset or adjustable
(user defined) output voltages.
When the VSEL pin is connected to +5 V, the PM6675S sets the switching section output
voltage to 1.5 V without the need of an external divider.
Applications requiring different output voltages can be managed by PM6675S simply setting
the adjustable mode. Consider that if the VSEL pin voltage is higher than 4 V, the fixed
output mode is selected. When connecting an external divider to the VSEL pin, it is used as
negative input of the error amplifier and the output voltage is given by expression (20).
Equation 20
The output voltage can be set in the range from 0.6 V to 3.3 V.
The NOSKIP is the power saving algorithm selector: if tied to +5 V, the forced-PWM (fixed
frequency) control is performed. If grounded or connected to VREF pin (1.237 V reference
voltage), the Pulse-Skip or Non-Audible Pulse-Skip Modes are respectively selected.
