The Digilent VRM (Voltage Regulator Module) is a battery-friendly switching voltage regulator capable of providing up to 6A of current at 5V or 3.3V. The input voltage can be stepped down from sources as high as 15V. It is ideal for use in mechatronics applications to efficiently regulate battery voltage, or in any application where a clean step down is required.
 

Features include:

• Up to 6A synchronous step down switching regulator
• Selectable 5V or 3.3V output voltage
• Input voltage range of 5-15V
• 479kHz internal switching frequency
• Switching synchronization to anexternal clock

Functional Description

The Digilent VRM is designed to provide regulated 5V or 3.3V power using an external power source such as a battery. The 6A maximum current is ideal for application from small control boards to large mechatronics projects. In particular, it is useful for projects utilizing Digilent boards requiring a 5V source, as both the 5V external rail and the 3.3V internal regulation can be achieved.

Note: The 6A output current rating depends on operating temperature. It may be necessary to provide additional heat sinking or fan cooling to achieve the full 6A output current in some situations.
