10. Power supply stabilization

This IC has a large output current, which causes deviation of the power line readily. To ensure stability, it is necessary

to insert a capacitor with sufficient capacitance between the VM pin and GND. To eliminate the high-frequency noise

due to switching, insert a ceramic capacitor of about 0.1μF as near as possible to the pin between VM (pin 5) and GND

2 (pin 3).

When inserting diode in the power line to prevent breakdown due to reverse connection of power supply, select the

sufficiently large capacitance because the power line tends to develop deviation readily.

The VCC voltage that is a control power supply must also be fully stabilized by means of a capacitor when such voltage

tends to fluctuate because of routing.

11. Routing of a printed circuit board

Two pins are provided for each of VM, RF, and GND2 pins where large current flows. On the printed circuit board,

both of these pins should be connected and used. If the use of only one pin is possible in certain cases, use pins 3, 5, and

6.

GND3 that is a sub-GND (internal separation layer) should be connected with control GND or GND1 with the shortest

possible wiring.
