集成化OTL场输出级与逆程泵电源电路的设计特点(之二)——彩色多频同步显示器电路设计分析Ⅺ

Features in the Design of Integrated OTL Vertical Deflection Output Circuit and Flyback Pump Supply (2)

由TDA1170N与外部场偏转线圈和s校正电容组成的集成化场偏转输出电路,是一种无输出变压器型(OTL)功率放大器,它由IC内部的乙类单端推挽式电路(SEPP)和消隐脉冲形成与逆程泵电源等组成。

The Integrated vertical deflection output circuit includes TDA1170N, external vertical deflection coil and S correction capacitor. It is an output-transformer-less (OTL) power amplifier, and it consists of class B single-ended push pull (SEPP) circuits, blanking pulse generator, flyback pump supply and etc. in the IC chip.
