MAX5026

The MAX5026 is designed as evaluation kit (EV kit) which 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 lownoise performance of the device. It contains a boost converter. The circuit provides a +30V output with less than 2mVp-p highfrequency ripple from a +3V to +11V input voltage, and delivers up to 6mA.

The MAX5026 has many features. The first one is +3V to +11V input voltage range. The second one is output voltage adjustable output voltage up to +36V. The third one is it would have low switching noise. The fourth one is 500kHz switching frequency. The fifth one is less than 1mVp-p high-frequency output switching ripple at 2mA load. The sixth one is up to 6mA output current with +5V input. The seventh one is 6-pin SOT23 package. The eighth one is surface-mount construction. The ninth one is fully assembled and tested. That are all the main features.

The MAX5026 is a fully assembled and tested surface-mount board. Follow the steps below to verify board operation. Do not turn on the power supply until all connections are completed. Some point about the evaluating of it. The first one is verify that there is a shunt across JU1 (SHDN) pins 1 and 2. The second one is connect a voltmeter and load (if any) to the VOUT pad (and/or plug an oscilloscope probe into the oscilloscope jack). The third one is connect a +3V to +11V power supply to the VIN pad. Connect the power-supply ground to the GND pad closest to VIN. The fourth one is turn on the power supply and verify that the output voltage is approximately +30V. And so on. For more information please contact us.
