Product Details

The MAX5026 evaluation kit (EV kit) provides a +30V output voltage from a +3V to +11V input source. It delivers up to 6mA output current, depending on the input voltage. The MAX5026 is a constant-frequency, pulse-width-modulating (PWM), current-mode step-up voltage converter with an internal power switch that operates at 500kHz. This EV kit demonstrates the low-noise performance of the device.

The MAX5026 EV kit is a fully assembled and tested surface-mount circuit board. With modifications, this EV kit can also be used to evaluate MAX5025/MAX5027/MAX5028. The EV kit can be used to evaluate other output voltages by changing the feedback resistors.
