Specifications:

Input Voltage: DC 5-60V (output voltage must exceed input by at least 1V)

Output Voltage: 3.3V/5V/12V (selectable)

Peak Current: 3A

Continuous Current: Within 2A

Product Description:

Utilises original chips. The module delivers a peak current of 3A and a continuous output current within 2A. Heat generation increases proportionally with higher input voltages. At 50V input, it can sustain 2A output for 3.3V and 5V; 12V output is recommended within 1.5A. When selecting models, allow for thermal headroom to account for heat dissipation.

Precautions:

1. Input voltage must exceed output voltage; maintaining a voltage differential of at least 1V is optimal. Reverse polarity connection will damage the board.

2. Disconnect power before wiring to prevent sparking at high voltages, which risks damaging or shorting the chip.

3. Use sufficiently thick wiring to handle the rated current.

4. Protect inductive loads to prevent excessive back EMF exceeding the chip's tolerance.

5. Higher power usage approaches the maximum current, increasing heat generation. Ensure adequate heat dissipation during operation.

6. Without external cooling, continuous operating current should remain below 2A. Exceeding 2A necessitates supplementary cooling to prevent thermal shutdown.

7. Recommended operating voltage is below 56V. If supply voltage is unstable, spikes exceeding 60V may trigger the chip's internal overvoltage protection. Maintain a margin for stable operation.
