Description
The MAX850-MAX853 ICs are inverting, charge-pump DC-DC converters with low-noise, regulated outputs. Their low output ripple voltage makes these devices ideal for biasing the GaAs FETs commonly found in cellular telephone transmitters.
The MAX850 evaluation kit (EV kit) is a fully assembled and tested surface-mount board. The board is shipped with a MAX850 mounted, but it can be replaced by the MAX851, MAX852, or MAX853. Provisions are made for mounting two additional resistors, which are required for output voltages other than -4.1V. A special scope-probe socket is also mounted on the board, so output noise can be observed on an oscilloscope.
