Description

J11

VAUX

Auxiliary voltage.

Internally regulated 5 V voltage. It is used to supply the internal drivers and the

voltage reference.

K11

OS

Oscillator set.

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).

L2

VSENSE

Voltage sense.

Using this pin it is possible to recover the voltage drop on Vout track.

L3

VCC

VCC.

Controller voltage supply pin. The operative voltage range for the internal

controller is 4.5 V to 14 V
