Preliminary specification
Full bridge current driven vertical
deflection booster
TDA4867J
THERMAL CHARACTERISTICS
Note
1. To minimize the thermal resistance from mounting base to heatsink [Rth(mb-h)] follow the recommended mounting
instruction: screw mounting preferred; torque = 40 Ncm; use heatsink compound; isolation plate increases Rth(mb-h).
CHARACTERISTICS
VP = 12 V; Tamb =25 °C; VFB = 40 V; voltages referenced to ground (pin GND); unless otherwise specified.
