TDA8350Q/N6,112

Overview

The TDA8350Q is a DC-coupled vertical deflection and East-West output circuit designed for 90° and 110° color deflection systems operating at field frequencies of 50 to 120 Hz. It integrates a highly efficient Class G vertical output bridge, flyback switch, and an East-West driver. The device operates with a supply voltage (VP) range of 9 V to 25 V and supports a flyback supply (VFB) up to 60 V. Key electrical parameters include a peak-to-peak output current capability of 3 A, a differential input voltage of 1.8 V max, and a sink output current of 500 mA for the East-West stage. Thermal protection and short-circuit safeguards are built-in.

Feature Summary

• Highly efficient fully DC-coupled vertical output bridge circuit operating as a Class G system
• Integrated East-West output stage requiring only a single conversion resistor
• Built-in protections against output pin short-circuits, short-circuits to VP, and thermal overload
• Guard circuit output for picture tube screen blanking during flyback or fault conditions

Applications

• 90° and 110° color CRT deflection systems
• Vertical deflection output stages in television receivers
• East-West correction circuits for CRT displays

Procurement Notes

Verify component authenticity through authorized NXP channels. Confirm package integrity for the 13-PDBS form. Check manufacturing date codes as this specification supersedes January 1995 data. Ensure compatibility with existing PCB layouts using the DBS13P lead configuration.

Selection Notes

Select based on required vertical output current (up to 3 A p-p) and flyback voltage requirements (up to 60 V). Ensure the driving stage provides symmetrical current signals compatible with inputs Idrive(pos) and Idrive(neg). Verify that the application circuit includes necessary external components such as the RCON resistor and decoupling capacitors as specified in the datasheet application diagrams.

Part Context

The TDA8350Q belongs to the Philips/NXP TDA835x series of deflection output ICs. It is functionally related to variants like the TDA8351 and TDA8354, which offer similar vertical deflection capabilities but may differ in specific integration levels or packaging. This part specifically combines vertical deflection and East-West correction in a single 13-lead package.
