ADP1611
APPLICATION CIRCUITS
The circuit in Figure 27 shows the ADP1611 in a step-up
configuration. The ADP1611 is used here to generate a 15 V
regulator with the following specifications:
V IN = 3.5 V to 5.5 V
V OUT = 15 V
I OUT ≤ 400 mA
The output can be set to the desired voltage using Equation 2.
Use Equations 16 and 17 to change the compensation network.

applications. This circuit has +10 V, ?5 V, and +22 V outputs.
The +10 V is generated in the step-up configuration. The ?5 V
and +22 V are generated by the charge-pump circuit. During
step-up , the SW node switches between 10 V and ground
(neglecting forward drop of the diode and on resistance of the
switch). When the SW node is high, C5 charges up to 10 V. C5
holds its charge and forward-biases D8 to charge C6 to ?10 V.
The Zener diode, D9, clamps and regulates the output to ?5 V.

SHUTDOWN
Some battery-powered applications require very low standby
current. The ADP1611 typically consumes 10 nA from the
input, which makes it suitable for these applications. However,
the output is connected to the input through the inductor and
the rectifying diode, allowing load current draw from the input
while shut down. The circuit in Figure 28 enables the ADP1611
to achieve output load disconnect at shutdown. To shut down
the ADP1611 and disconnect the output from the input, drive
the SD pin below 0.4 V.

The VGH output is generated in a similar manner by the
charge-pump capacitors, C1, C2, and C4. The output voltage is
tripled and regulated down to 22 V by the Zener diode, D5.
