The resistance between V BUS and V CC supply should
be large enough to minimize the current sourced
directly from the input voltage line; value should be on
the order of hundreds of k ? . Through the supply
resistor, a current will flow to charge the V CC
capacitor. Once the capacitor is charged up to the

V CCUV+ threshold, the IRS254(01,11) enters the micro
start-up regime and begins to operate, activating the
Capacitance (uF)

The addition of the C OUT increases the amount of
energy that can be stored in the output stage, which
LO and HO outputs. After the first few cycles of
switching, the resistor connected between the output
and V CC will take over and source all necessary
current for the IC. The resistor connecting the output
to the supply should be carefully designed according
to its power rating.
V out ? 15 . 6 V
also means it can supply current for an increased
period of time. Therefore by slowing down the di/dt
transients in the load, the frequency is effectively
decreased.
With the C OUT capacitor, the inductor current is no
longer identical to that seen in the load. The inductor

current will still have a perfectly triangular shape, where
as the load will see the same basic trend in the current,
but all sharp corners will be rounded with all peaks
significantly reduced, as can be seen in Fig. 15
VCC Supply
Since the IRS254(01,11) is rated for 200 V (or 600 V),
V BUS can reach values of this magnitude. If a supply
resistor to V BUS is used, it can experience high power
losses. For higher voltage applications if the output
voltage is above VCCUV+ plus one diode drop an
alternate V CC supply scheme utilizing the micro-power
start-up and a resistor feed-back from the output can to
be implemented, as seen in Fig. 16.
