5.3 NOTE

There is a linear regulator on board, it allows to use one generator (only for the power section, in fact the IC

section is powered by the linear regulator); if the regulator is used close the J1, other wise it has to keep open.

Be careful measuring the efficiency with the linear regulator asserted.

At high current in the integrator configuration (around 20A), it can be seen an oscillation in the switching fre-

around 1Mhz, but anyway higher than switching frequency (five times).
