ADP1610
APPLICATION CIRCUITS
The circuit in Figure 27 shows the ADP1610 in a step-up confi-
guration that can be used to generate a 10 V regulator with the
following specifications: V IN = 2.5 V to 5.5 V, V OUT = 10 V, and
I OUT ≤ 400 mA.

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
the step-up operation, 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 output is set to the desired voltage using Equation 1.
To change the compensation network, see Equation 17 and
Equation 18.

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.

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 ADP1610
to achieve output load disconnect at shutdown. To shut down
