MC33063A: Power consumption in idle mode

Part Number: MC33063A


I need help to reduce power consumption of the attached MC33063A Circuit.

I am measuring current as shown in the image and it is ~6-7mA. No load condition.

Nothing else is connected except relay coil positive terminal at +12V. Relay is OFF.

Rectifier Output: 32VDC

Is the 6-7mA current consumption expected when there is no load except 5V LDO connected at it`s output?

Any help on this circuit would be really helpful.
