DC-DC step-down power module current 3A 12V to 5V 3.3V
The DC-DC module efficiency up to 92%, on-board ultra-durable high-precision potentiometer, adjust the output voltage directly.
Input and output terminals used in the form of wiring. Power input with anti-reverse diode, even when the power accidentally reversed, it will not damage the module.Onboard power indicator LED as output.
Input and output are made of high-end dedicated high-frequency low-impedance switching power supply electrolytic capacitor (LOW ESR), to ensure that the output ripple is less than 50mV (pure resistive load, 5V, 3A time). The advantage of this capacitor equivalent series resistance is low, you can effectively filter out glitches in switching power supply.
Description:
- Input voltage range: 12V (minumum 7V, maximum 25V)
- Output voltage: 5V 3.3V
- Maximum output current: 3A
- Operating frequency: 380KHZ
- Maximum efficiency: 92%(on 5V power line)
- Output short circuit protection, output short circuit and will not even damage the module.
- Overheat protection, over temperature limits of the automatic protection IC.
- Pins On/Off, ADJ and SW are just pass-through lines. The power supply is not adjustable nor switchable
Note:
Make sure when using the input voltage higher than the output voltage of about 1.5V in order to ensure adequate power output.
