Overview

The STK390-120 is a high-accuracy convergence correction circuit hybrid IC designed to complement the advances in modern high-resolution video projectors and CRT displyas. It incorporates a convergence circuit that operates at high frequency with a corresponding high slew rate, without the increase in power dissipation and mounting, space that discrete devices would entail. It also features a built-in supply switching circuit for high efficiency.

Features

• High absolute maximum supply voltage (VCC max = ±44V)

• Low thermal resistance (θj-c=2.7°C/W)

• High temperature stability (strengthened idling current temperature compensation)

• Reduced correction coil inductance to improve stability (over the range fH≤85kHz)

• Supply switching circuit built-in to enable large-scale decreases in power dissipation

• Improved convergence characteristics for CRT displays

Applications

• Video projectors

• Ultrahigh definition CRT displays
