The MAX797 evaluation kit (EV kit) is a preassembled

and tested demonstration board that embodies the stan-

dard 3.3V application circuit. The board comes config-

ured to accept battery voltages between 4.5V and 28V,

but can be reconfigured for voltages between 4.5V and

30V by substituting MOSFETs with higher breakdown

voltage ratings.

The standard board is guaranteed to deliver at least 3A

of load current. To modify the load-current capability,

change the sense-resistor (R1) value and re-size the

external components according to Table 1 in the

MAX796/MAX797/MAX799 data sheet.

The main output voltage comes preset to 3.35V (nomi-

nal). To select 5V operation, move jumper J3 to position

1-2. For operation in adjustable mode, install resistors

R4 & R5 and remove the jumper. There is a small PC

trace jumper that shunts J3 on the board. This

default jumper must be cut apart for either

adjustable-mode or fixed 5V operation. Don’t operate

the circuit if a jumper or resistor divider has not been

installed, as this will damage the IC due to output over-

voltage.

In addition to the standard components, the EV kit has

some extra pull-up and pull-down resistors (R4–R8) to

set default logic input levels. These resistors can usual-

ly be omitted in the final design.
