MC33063A: External switch FET for Vout > 40V

Part Number: MC33063A



Regarding to external FET on MC33063A, my customer is asking a question.

Their requirement :

Vin: 15V, Vout : 150V ,0.8W (Io=5.3mA)

(It is used for PIEZO driver.)


According to datasheet(page8), external switch configurations is described.

But it seems that it is for higher peak current.


Is this device supported Vout >40V( for example: 150V) with external switch(FET)?
