This data sheet provides two predesigned standard
application circuits. The circuit of Figure 1 produces 12V
at 120mA from a 5V input. Table 1 lists component val-
ues and part numbers for both the MAX606 and MAX607
variations of this circuit. The circuit of Figure 2 produces

Power Ground. Source of n-channel power MOSFET.
Feedback Input. Connect to IN for 5V output, to GND for 12V output, or to a resistive voltage divider between
OUT and GND for an adjustable output between IN and 12.5V.
Shutdown Input, Active Low. Connect to GND to power down or to IN for normal operation. Output power FET
is held off when SHDN is low.
Supply Voltage Input: 3.0V to 5.5V
Analog Ground
Soft-Start Input
Output. Always connect directly to the circuit output.

OUTPUT
5V at a typical output current of 180mA from a 3.3V
input. Each application circuit is designed to deliver the
full rated output load current over the temperature range
listed. Component values and part numbers for this cir-
cuit are listed in Table 2. See Table 3 for component
