STMicroelectronics has introduced its vertical-deflection booster for Slim CRTs. 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 vertical booster drives the vertical coil of the deflection yoke to scan the electron beam over the screen. This, in conjunction with horizontal deflection and beam modulation, creates viewable images. 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. The STV8179F provides a peak-to-peak current up to 3.6A in operating mode.

The advanced design of the STV8179F also sustains high output flyback voltages, up to 100V, to allow short retrace times required in 2H and High-Definition TVs. The 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, the company reports.
