TDA4800 Overview
plastic DIL-bent-SIL power package; GENERAL DESCRIPTION TDA4800 The TDA4800 is an integrated circuit for vertical deflection primarily in monitors (and TV receivers). The plete circuit consists of 11 main functional blocks as shown in Fig.1.
TDA4800 Key Features
- Fully integrated, few external ponents
- RC oscillator with wide sync range of 1 : 3 (e.g. 50 to 150 Hz)
- Synchronization by positive or negative going sync pulse
- Blanking pulse duration is determined externally
- Dual frequency criterion for automatic amplitude switch-over (e.g. 50 to 60 Hz)
- Guard circuit for screen protection
- Sawtooth generator with buffer stage supplied by external voltage
- Preamplifier
- Power output stage with thermal and SOAR protection
- Flyback generator
