Product Details

The MAX1932 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed circuit board (PCB). The EV kit contains a MAX1932 step-up switching regulator that includes an 8-bit DAC with an SPI™-compatible serial interface. The output of the step-up switching regulator is configured for a range of 40V to 90V and can provide up to 2mA. The EV kit is powered from a DC supply providing 4.5V to 5.5V. The EV kit can be reconfigured for an input voltage down to 3V.

The SPI-compatible serial interface can be connected to an IBM-compatible PC parallel port for evaluation. Windows® 95/98/2000-compatible software provides a user-friendly interface to demonstrate the features of the MAX1932 IC. The program is menu driven and offers a graphics interface with control buttons.

The MAX1932 EV kit features current-limit protection for the output. The MAX1932 thin QFN package and small external components permit the circuit area to be less than 0.6in x 0.9in.

Applications

  • Fiber Optic Network Equipment
  • Laser Range Finders
  • Optical Receivers and Modules
