HV857 Application Note
Circuit Selector Guide for Non Audible Noise Sensitive Applications:
1
(Handheld products, PDAs, GPS, 2-way pagers, MP3)
No series resistor is used for the following circuits (R=0
). Also see Figure 1 and Table 3.
External components used for Circuits 1 to 9:
The following table provides the value for external components used in Figure 1. The manufacturer and part number for the inductor is
also provided. If other value inductors are used, the circuit will need to be reoptimized.
