NXP Semiconductors TDA4867J
The TDA4867J is a power booster for use in colour vertical deflection systems for frame frequencies of 50 to 200 Hz. The circuit provides a high CMRR current driven differential input. Therefore, the TDA4867J requires no external coupling capacitor and operates with one supply voltage (VP) and a separate adjustable flyback supply voltage (VFB) only.| Part No. | TDA4867J |
