Overview
The STK392-020 is a hybrid IC for video projector
convergence correction. Since this IC integrates three
output amplifier circuits in a single package, the six
convergence correction output circuits, i.e., the vertical
and horizontal directions for each CRT of the RGB can be
formed from only two ICs.
Features
• Three output amplifier circuits integrated in a single
22-pin package
• High absolute maximum supply voltage
(VCC max = ±44 V)
• Low thermal resistance (qj-c = 2.1 °C/W)
• High thermal stability (TC max = 125°C)
• Isolated early stage and output stage power supplies
• Output stage power supply switching supports high
efficiency designs.
• The input system, power supply system and output
system pins are isolated in the pin arrangement, thus
reducing the influence of the pattern layout on the
characteristics and easing design.
• Since constant current circuits are used in the pre-driver
stage, operation is stable with respect to the power
supply switching.
• The Sanyo convergence correction circuit product
lineup (the STK392-000 series) handles a wide range of
end-product classes. Therefore, the same PCB can be
used for end products from popularly-priced units to
top-of-the-line models.
