M78AR12-0.5 - Minmax

Description: The M78AR-0.5 series is a new range of switching regulators designed as a drop-in replacement for old LM78xx linear regulators with low efficiency.The very high efficiency of these step-down converters allow an operating temperature up to 80℃ at full-load without need of any heatsink. The regulators come in a package which fits in the standard TO-220 footprint of linear regulators.

M78AR12-0.5 Frequently Asked Questions (FAQs)

  • Minmax recommends a PCB layout with a solid ground plane and thermal vias under the device to ensure efficient heat dissipation. A minimum of 2oz copper thickness is recommended.
  • Ensure proper airflow, use a heat sink if necessary, and avoid blocking the airflow around the device. Also, follow the recommended PCB layout and thermal management guidelines.
  • Minmax recommends derating the input voltage by 10% to ensure reliable operation and to account for voltage tolerances. For example, if the input voltage is 12V, derate it to 10.8V.
  • Yes, the M78AR12-0.5 is designed to withstand vibrations up to 10G. However, it's essential to ensure the device is properly secured to the PCB and the PCB is securely fastened to the system to prevent damage.
  • The typical start-up time for the M78AR12-0.5 is around 10ms. However, this may vary depending on the input voltage, output load, and system configuration.
