Product Description: Adopting original big brand chip, Samsung capacitor input and output up to 3.5A (output not more than 3.5A when buck, input not more than 3.5A when boost). Built-in 4 low resistance MOS, so that the module can be in a very small volume to achieve a larger power lift voltage output, the module ultra-low power consumption also makes it possible to apply in battery-powered applications.

Parameter:
VIN+: DC input positive 3V-20V
GND: DC input negative terminal, connected with the output negative terminal
OUT+: DC output positive
GND: DC output negative terminal, connected to the input negative terminal.
EN (on the back of the board): module work enable, low level off, the default output work
Maximum 3.5A working current
0.1mA quiescent current
50μA shutdown current
Up to 95% conversion efficiency
450KHZ low ripple
Output short circuit protection
Built-in over-temperature protection

Use must see:
1. Input and output maximum 3.5A (buck output does not exceed 3.5A, boost input does not exceed 3.5A). Note that the input and output voltage are less than 4V, the current will drop.
2. It is best to disconnect the power supply when wiring, otherwise when the voltage is high, it is easy to spark, which will have a certain risk of breakdown chip.
3. The wiring should not be too thin, to ensure that the wire can withstand the corresponding current.
4. Inductive loads to do a good job of protection, to avoid excessive reverse electromotive force beyond the chip to withstand the range of - module using the greater the power, the current is closer to the maximum current. Heat will be greater, use attention to heat dissipation.
5. In the absence of external heat dissipation, the continuous use of current is recommended below 3A, more than 3A will require additional heat dissipation, otherwise it will overheat to protect the output.
6. The use of voltage is recommended below 19V, should be if the supply voltage is not very stable, spike voltage more than 20V will trigger the chip internal over-voltage protection, for stable operation, appropriate to leave some margin.
