DESCRIPTIONThe L6590isa monolithic switching regulator de-
signedin BCD OFF-LINEtechnology, ableto operate
with wide range input voltage andto deliver upto
15W output power. The internal power switchisa lat-
eral power MOSFET witha typical RDS(on)of 13Ω
anda V(BR)DSSof 700V minimum.

TYPICAL APPLICATION CIRCUIT
L65902/23
DESCRIPTION (continued)
The MOSFETis source-grounded, thusitis possible build flyback, boost and forward converters.
The device can work with secondary feedback anda
2.5V±2% internalreference,in additiontoa high gain
error amplifier, makes possible also the usein appli-
cations either with primary feedbackor not isolated.
The internal fixed oscillatorfrequency andthe integrated
non dissipative start-up generator minimize the external
component count and power consumption.
The deviceis equipped witha standby function that
automatically reduces the oscillator frequency fromto22 kHz under light load conditionsto enhance
efficiency (Pin <1W@ Pout= 0.5W with wide range
mains).
Internal protections like cycle-by-cycle current limiting,
latched output overvoltage protection, mains undervolt-
age protection (SMD version only) and thermal shut-
down generatea 'robust' design solution.
TheIC usesa special leadframe with the ground pins
(6,7 and8in minidip,9 to16in SO16W package)in-
ternally connectedin orderfor heattobe easily re-
moved from the silicon die.An heatsink can thenbe
realized by simply making provisionof few cm2of
copperon the PCB. Furthermore, the pin(s) closeto
the high-voltage one are not connectedto ease com-
pliance with safety distanceson the PCB.
