【Function】
DC-DC boost power supply module dedicated to high-current boost occasions, an extremely wide range of input voltage protection function, suitable as car PC, laptop power supply, or movement of the PC backup power booster, such as the battery voltage (9 ~ 12V) rose to 16V, 18,20 V, 24V, 36V and so on. actual test output voltage can be boosted up to three times the input voltage. measured at 1A basic no heat, the greater the operating voltage heat greater conversion efficiency of> 90%.
First, the main features of
(1) less peripheral circuit;
(2) Wide input voltage range: 3.0V ~ 40.0V;
(3) internal integrated 52kHz crystal oscillator circuit;
(4) internal flow, low pressure, temperature protection function;
(5) Current mode operation;
(6) has a soft-start function;
(7) with current mode operation to improve the linear regulator, the current limit, the sensitivity of detecting the resistance portion;
(8) the maximum current of the output NPN switch 3A, the maximum output voltage of 65V.
Second, the specific operation: elevated potentiometer counterclockwise rotation of the output voltage, reduce the potentiometer inverse clockwise rotation of the output voltage. Electronic DIY requires a certain amount of expertise and ability, please exercise caution to avoid damage caused by human factors (such as the input positive and negative reversed, output short circuit will be burned over a certain period of time)
Note: the the boost module's output voltage is always higher than the input voltage. To get a large output current, you must use a large input current.
Product interface pictures: IN GND respectively connected to the input and ground, the OUT GND, respectively, then the output and ground.
