Maximum Substrate Charge Measurements

This chapter refers to Qmax parameter measurements.

The DDA002C has been connected according to the

Figure 60 during Qmax measurements. This connection

allows measuring just only the substrate current that flows

during the L1 demagnetization. Once the current is

integrated one can get maximum charge that can flow to the

substrate without causing device malfunction. Measure−

ments didn’t show that the Qmax depends on the operating

frequency of the device. Measurements have been done for

TA = 125°C.
