<strong>MC34152</strong>, <strong>MC33152</strong>, <strong>NCV33152</strong>LAYOUT CONSIDERATIONS<strong>High</strong> frequency printed circuit layout techniques areimperative to prevent excessive output ringing andovershoot. Do not attempt to construct the driver circuiton wire–wrap or plug–in prototype boards. Whendriving large capacitive loads, the printed circuit boardmust contain a low inductance ground plane to minimizethe voltage spikes induced by the high ground ripplecurrents. All high current loops should be kept as short aspossible using heavy copper runs to provide a lowimpedance high frequency path. For optimum driveperformance, it is recommended that the initial circuitdesign contains dual power supply bypass capacitorsconnected with short leads as close to the VCC pin andground as the layout will permit. Suggested capacitors area low inductance 0.1 µF ceramic in parallel with a 4.7 µFtantalum. Additional bypass capacitors may be requireddepending upon Drive Output loading and circuit layout.Proper printed circuit board layout is extremelycritical and cannot be over emphasized. Figure 19.
