Vertical Deflection Output Circuit
Overview
The LA7845N is a vertical deflection output IC for TVs and
CRT displays with excellent image quality that use a BUS
control system signal processing IC. This IC can drive the
direct (even including a DC component) deflection yoke with
the sawtooth wave output from the BUS control system signal
processing IC. When used in conjunction with Sanyo’s LA7615
series of BUS control system signal processing ICs for TVs,
this IC can process all color television signal system functions
through the BUS system. Because the maximum deflection
current is 2.2 Ap-p, the LA7845N is suited for large screen
sets, being capable of driving screens ranging from 33 inches
to 37 inches.
