7. Typical Connection Diagram of HPA1000 Isolated Pulse Width Modulation Amplifier

Typical Connection Diagram
Fig 4  HPA1000 Typical connection Diagram
Notes:Power supply VS should have sufficient bypass capacitors to ensure proper operation, otherwise it may be unstable and reduce efficiency, and the output may be oscillated. Vs power supply should connect with a 1uF at least ceramic capacitor paralleled with a low ESR value bypass capacitor. The capacitance should be at least 10uF/A. for VCC also requires a 0.1uF~0.47uF ceramic capacitor and a low ESR value of 6.8uF~10uF parallel bypass capacitor, All bypass capacitors should be connected as close as possible to the corresponding power supply root.
