应用/用途

描述

The MAX797 evaluation kit (EV kit) is a preassembled and tested demonstration board that embodies the standard 3.3V application circuit. The board comes configured 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 (nominal). 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 overvoltage.

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 usually be omitted in the final design.
