S tandard Applic ation Circ uits
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
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
suppliers’ phone and fax numbers.

NAME
FUNCTION
1
PGND
Power Ground. Source of n-channel power MOSFET.
2
FB
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.
PIN
3
SHDN
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.
4
IN
Supply Voltage Input: 3.0V to 5.5V
8
LX
Drain of n-channel power MOSFET
7
OUT
Output. Always connect directly to the circuit output.
