DESCRIPTION

The EV9361DJ-00A evaluation board is a fully assembled and tested PCB that demonstrates the performance of MP9361, a high performance, regulated charge pump converter. Its input voltage ranges from 2.8V to V OUT. The output voltage is regulated to a fixed 5V. No external inductor is required for simplicity and compactness. Internal soft-start circuit effectively reduces the in-rush current both while start-up and mode change. This device, available in a TSOT23-6 package, provides a very compact system solution.

Connect the positive terminal of the load to VOUT pin, and the negative terminal of the load to GND pin 2. Connect the positive terminal of the power supply output to the VIN pin and the negative terminal of the power supply output to the GND pin 3. Preset the power supply output to 2.8V to 5V and turn off the power supply 4. Turn on the power supply. The EV9361DJ-00A will automatically start up 5. To use the Enable function, apply a input to the EN pin. Drive EN higher than 1.5V to turn on the regulator or less than 0.4V to turn it off 6. The switching frequency on the board is preset to 1.3MHz
