Figure 8. Placement of VCCH Capacitor.

Figure 7.

Preferred Routing of Optocoupler and Traces to FEEDBACK Pin.

Small Signal Bypass Capacitors

Please refer to Figure 5 Note the location of the small signal bypass

capacitors (highlighted) for the FEEDBACK, DT/BF, IS, VREF, OV/UV

and VCC pins, which allow short traces to their pin connections and to

the GROUND pin. Note that there is no connection between the

GROUND pin and the SOURCE pin or the B- bus on the printed circuit

board.

VCCH Bypass Capacitor

Please refer to Figure 8. Note the location of the VCCH capacitor

(highlighted) which allows short connections to the HB pin and the

VCCH pin.

Drain to Source High-Voltage Bypass Capacitor

Please refer to Figure 9. Note the location of the B+ to B- high-volt-

age bypass capacitors (highlighted) placed at the IC, minimizing the PCB

trace length to the D and S pins.
