APPLICATION
64-Pin SQFP test board for typical 2" or smaller HDD (shown with external phase detector for spindle speed control and
external PWM for VCM DAC)
VCM Design Equations:
(1) Transconductance (G
mv
)
(2) Output Retract Current
Spindle Design Equation:
(3) Transconductance Loop Compensation
(4) Refer to AN93-1 for all servo equations.
