Alongside traditional linear amplifiers (Class AB), ST also develops and
markets a family of vertical deflection boosters with the advanced "Class D"
mode of operation (based on Pulse Width Modulation). In production test,
physical access has become more difficult for traditional probing techniques,
such as in-circuit or flying probe testers, yet board complexity and
semiconductor packaging density continue to increase.national.

The new vertical deflection booster utilizes ST's
proprietary architecture based on 'external flyback,' which decreases the
supply voltage -- and thus reduces the dissipation rate in the IC -- with no
impact on the flyback voltage. with links to

The STV8179F meets the need in large -size, reduced-depth CRT monitors for high
output-current levels and flyback voltages, coupled with low heat dissipation.
The STV8179F builds on the success of its market-proven predecessors,
TDA8177F and STV9379FA, and, as a first-to-market product, it clearly
demonstrates the Company's determination to invest in products supporting the
latest CRT technologies. For high-availability systems that require continuous monitoring,
designers can now use the existing JTAG bus for embedded analog measurement .
By adding this component to the board, multiple point voltages can be
accessed even when extensive EMI (electromagnetic interference) shielding is
used or there is no physical access to the board. National's leading-edge
products include power management circuits, display drivers, audio and
operational amplifiers, communication interface products and data conversion
solutions .

In Slim CRT displays,
very high output currents are needed to drive the coil, as the beam swings
over wider deflection angles, compared to conventional CRTs.
