Name Function
Description
Auxiliary voltage.
J11 VAUX Internally regulated 5 V voltage. It is used to supply the internal drivers and the
voltage reference.
Oscillator set.
K11
OS
Connecting a resistor from this pin to SGND or to VAUX, the switching frequency
can be increased or decreased.
In OVP status the pin is pulled to 4.5 V (latched mode only).
Voltage sense.
L2 VSENSE
Using this pin it is possible to recover the voltage drop on Vout track.
VCC.
L3 VCC Controller voltage supply pin. The operative voltage range for the internal
controller is 4.5 V to 14 V
