To obtain Hall bias from VCC, carry out 1/2×VCC bias as shown in the figure. Linear driving is made through voltage control of the coil by amplifying the Hall output. When the Hall element output is large, the startup performance and efficiency are improved. Adjustment of the Hall element can reduce the noise further. To obtain Hall bias from the HB pin, carry out constant-voltage bias at about 1.5 V. which enables the Hall element to generate the stable Hall output satisfactory in temperature characteristics. The Hall output amplitude is adjusted with R1. (In the case of VCC = 12 V, *2 proves advantageous in terms of heat generation in IC.) This applies to the case of MFP-10S. Keep this open when not used. When the wiring from the Hall output to IC Hall input is long, noise may be carried through the wiring. In this case, insert the capacitor as shown in the figure.
