DESCRIPTION
(continued)
The MOSFET is source-grounded, thus it is possible
to build flyback, boost and forward converters.
The device is meant to work with secondary feed-
back for tight tolerance of the regulated output volt-
age.
The internal fixed oscillator frequency and the inte-
grated non dissipative start-up generator minimize
the external component count and power consump-
tion.
The device is equipped with a standby function that
automatically reduces the oscillator frequency from
65 to 22 kHz under light load conditions to enhance
efficiency (P
in
< 1W @ P
out
= 0.5W with wide range
mains).
Internal protections like cycle-by-cycle current limit-
ing, latched output overvoltage protection, mains un-
dervoltage
protection
and
generate a 'robust' design solution.
The IC usesa specialleadframe with the ground pins
(6, 7 and 8) internally connected in order for heat to
be easily removed from the silicon die. An heatsink
can then be realized by simply making provision of
few cm
2
of copper on the PCB. Furthermore, the pin
close to the high-voltage one is not connected to
ease compliance with safety distances on the PCB.
