DESCRIPTION

The EVM3606A-QV-00A is an evaluation board for MPM3606A, a synchronous rectified, step- down module converter with built-in power MOSFETs, inductor and two capacitors. The evaluation board can deliver a 0.6A continuous output current with excellent load and line regulation over a wide input supply range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection and thermal shut down. The MPM3606A is available in a space-saving QFN20 (3mm x5mmx1.6mm) package.

Connect the positive and negative terminals of the load to the V OUT and GND pins, respectively. 2. Preset the power supply output between 4.5V and 21V, and then turn off the power supply. 3. Connect the positive and negative terminals of the power supply output to the V IN and GND pins, respectively. 4. Turn the power supply on. The board will automatically start up. 5. To use the Enable function, apply a digital input to the EN pin. Drive EN higher than 1.4V to turn on the converter, or less than 1.25V to turn it off.
