Note: In the oscillation system of this IC, a constant discharging current of 8.4mA
flows the timing capacitor during triangular wave fall. Therefore, note that a
small maximum ON duty (large dead band) leads to a large supply current.
Refer to the equations of oscillation frequency and supply current for details.
