Application Circuit Examples
[1] Application circuit (Step-up circuit)
The figure shows a step-up circuit that converts a 3 V input to a 5 V output.
The AN8016NSH output stage has a totem pole circuit configuration, and can directly drive an n-channel
MOSFET while minimizes switching loss and increasing efficiency. In this case, replace the npn transistor with an
n-channel MOSFET in above circuit.
[2] Notes on direct n-channel MOSFET drive
1. Select an n-channel MOSFET with a low input
capacitance.
The AN8016NSH was designed to drive bipolar
transistors, and adopts a circuit structure that can pro-
vide a constant-current (50 mA maximum) output
source current. Furthermore, it has a sink current ca-
pacity of about 50 mA. This means that designs must
be concerned about increased power dissipation due
to increased rise and fall times. If problems occur, an
inverter may be inserted as shown in figure 1 to pro-
vide amplification.
2. Use an n-channel MOSFET of a low gate threshold
voltage.
Since the AN8016NSH Out pin high-level output
voltage is V
CC
1.0 V (minimum), a low V
T
MOSFET
with an adequately low on-resistance must be used.
Also, if a large V
GS
is required, one solution is to use
a transformer as shown in figure 2, and apply a volt-
age of twice the input voltage to the IC's V
CC
pin.
