APPLICATION CIRCUITS
All-Surface-Mount, Single-Cell to 5 V Converter
This is a very simple, compact, low-part-count circuit that takes
a single alkaline 1.5 V cell input and produces a 5 V output.
The output current should be kept to 10 mA or less to conserve
battery life.

All-Surface-Mount, 3 V to 5 V Step-Up Converter
Similar to the previous circuit, this circuit takes a 3-volt input
and provides a 5 V output at 40 mA. As in the single-cell version,
the circuit is compact and uses only four external components.

All-Surface-Mount, 9 V to 5 V Step-Down Converter
Featuring the same low parts count of the step-up design, this
circuit is the complement to the preceding one. The 220
resistor programs the current limit to around 600 mA.

1.5 V to
5 V Dual-Output Step-Up Converter
This circuit works from a single 1.5 V cell and provides simulta-
neous outputs of +5 V and –5 V. The accuracy of the negative
output suffers slightly because of the extra diode drop of around
0.4 V.

All-Surface-Mount Flash Memory VPP Generator
Figure 34 shows a circuit that can generate the programming
voltage, VPP to program flash memory. The key components
are the MOSFET and the bipolar transistor. These two devices
form a switch that, when ON, allows the ADP1110 to power-up
and function as a step-up converter. The output is +12 V at 120
mA. When the MOSFET switch is OFF, the output of the
circuit drops to just under +5 V thereby disabling the program-
ming capability.
Care should be taken so there is no short-circuit-current limiting
in the circuit in either operating mode.
