  • Sale
  • Regular price $4.29

This PWM buck (step-down) DC/DC converter module will provide 1.25V to 36V continuously adjustable output voltage at up to 5A current with a 4V to 38V input. With its XL4015 DC-DC converter, it provides high efficiency, low ripple and excellent line and load regulation.

This module is ideal for regulating 12V, 18V or 24V battery voltage down to the 12V, 9V, 5V or 3.3V levels required by many electronic circuits. For example, it could step a 12V car battery down to 5V for USB-powered devices such as cell phones or Arduino microcontrollers.
