Input voltage range:7-32VDC Output voltage range : 1.25V to ( input voltage -0.3V) Maximum output current : 3A Output ripple parameters : <100MV Conversion efficiency : A grade ≥ 84% Class B ≥ 69% Output short circuit protection : OK Output current protection point : A Class 4.6A B -class 4.2A Load Regulation : A grade ≥ 3% class B ≥ 5% Working temperature : -10 ~ +45 ? Note 1. Input and output leads may not be reversed. 2. The standard way DC-DC power output is 5V/3A (at 12V input) that the chip supports 15W load. Therefore when the output voltage is increased to 5V the current load capacity of the output is less than 3A the specific load capacity number A the output voltage is determined by how much as long as the total does not exceed 15W power capacity can be. 3. When the output current is greater than a certain value the power module will have a higher temperature if there is high demand for temperature it is recommended to increase the heat sink or fan-cooled. 4. When operating at maximum load the chip surface temperature is high do not touch. 5. When the load is greater than 3A but less than its current point 4.6A overcurrent protection this is a chip inrush current area this area is not allowed to chip in this state long-term work used to attention. 6. In order to use a more secure we recommend both output and input plus online 3A fuse.
