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 R_DS(on) of 13Ω
and a V_(BR)DSS of 700V minimum.
