Usage Notes (continued)
2. Select an n-channel MOSFET having a low gate
threshold value
The high-level output voltage of out pin of the
AN8017SA is V
CC
1.0 V minimum, so that it is
necessary to select a low V
T
MOSFET having a suffi-
ciently low on-state resistance in accordance with the
using operating supply voltage.
If a larger V
GS
is desired, there is a method to apply
the double-voltage of the input to the IC's V
CC
pin by
using the transformer as shown in figure 2.
[3] In order to realize a low noise and high efficiency, care should be taken in the following points in designing the
board layout.
1. The wiring for ground line should be taken as wide as possible and grounded separately from the power system.
2. The input filter capacitor should be arranged in a place as close to V
CC
and GND pin as possible so as not to allow
switching noise to enter into the IC inside.
3. The wiring between the Out terminal and switching device (transistor or MOSFET) should be as short as possible
to obtain a clean switching waveform.
4. In wiring the detection resistor of the output voltage, the wiring for the low impedance side should be longer.
[4] There is a case in which this IC does not start charging to the S.C.P. capacitor when the output is short-circuited
due to the malfunction of U.V.L.O. circuit biased by V
CC
that has ripples generated by turning on and off of the
switching transistor. The allowable range of the V
CC
ripple is as shown in the following figure. Reduce the V
CC
ripple
by inserting a capacitor near the V
CC
terminal and GND terminal of this IC so that the V
CC
ripple is in this allowable
range. However, this allowable range is design reference value and not the guaranteed value.
