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-

voltage bypass capacitors (highlighted) placed at the IC, minimizing

the PCB trace length to the D and S pins.
