The K120503 is a DC-DC converter module designed to efficiently regulate voltage. It steps down a higher DC voltage (input range: 8V to 22V) to a stable 5V output voltage, with a maximum output current of 3A. This makes it a versatile tool for powering low-voltage (5V) devices from a higher voltage source, typically 12V in automotive applications or battery packs.

Specification 

• Input Voltage Range: 8V to 22V DC – Provides flexibility in input voltage sources, accommodating fluctuations within a range.
