TYPICAL APPLICATION CIRCUIT

DESCRIPTION

The L6590 is a monolithic switching regulator de-

signed in BCD OFF-LINE technology, able to operate

with wide range input voltage and to deliver up to

15W output power. The internal power switch is a lat-

eral power MOSFET with a typical RDS(on) of 13Ω

and a V(BR)DSS of 700V minimum.
