DESCRIPTION
The TDA2270 is a high efficiency monolithic output
stage for vertical deflection circuits in TVs and
monitors. Driving the vertical windings directly, the
device contains a power amplifier, flyback gener-
ator, voltage reference and thermal protection cir-
cuit.
The TDA2270 is supplied in a 16-pin DIP with the
four center pins connected together and used for
heatsinking.
