TPS63070 3.3V/5V/9V USB/lithium battery automatic lifting booster power supply module 9V voltage pressure module

This module adopts the TPS63070 power supply chip solution, with stable performance, small ripples, with a maximum 2A current output capacity, the module has PWM mode, and the PFM power saving mode. Users can adjust themselves (default PWM mode shipment, PFM power saving requires PFM power saving.Users in the mode can switch by themselves).The module design has three fixed voltage outputs, which are 3.3V, 5V, and 9V, and leave the ADJ pad, which can be used to change the output voltage for users to welded different resistance values ​​by themselves.

The working voltage of as low as 2.0V can be applied to the power supply scene of the post -stage sensor with a small voltage voltage to 3.3V and 5V.In the large current application, pay attention to the heat of the module, and increase the heat dissipation to the module according to the actual situation.If there is no special explanation, the following parameters are tested under the PWM mode (recommended work mode).

Notice:

The output voltage selection can only be connected to a jumper pad in a short period of time. You cannot shorter multiple pads at the same time, and the three pads and AD "resistance can only be selected to work; ADJ configuration resistance formula: ADJ = (15000*voutt (15000*vout) /0.8-15000 4. About output

1. The module is an automatic lifting booster module. It can be used under the input voltage conditions of 2V-16V. The output is 2.5V-9V. There are three fixed voltage output of the module.Fifth, 5. Make use suggestions:

The module MAX output current is 2A, and the MAX output current is recommended under the common parameters.(Long running is recommended to control the heating power at about 0.5W under the condition of natural heat dissipation)

6. About ripples

It is normal to use different power supply to measure the ripples when the same output parameters are in the same output parameter. The ripples will increase significantly when using the inferior power supply power supply. If there are users who require the output rippleGood power supply or power supply with lithium battery.

Seven, about fever

When the module temperature rises, its work efficiency will decrease further. In order to avoid module burning, it is very important to use heat dissipation measures to use heat dissipation measures when the work that requires a large power/current.

When the input power is sufficient, the output voltage occurs rapidly or decreased by the voltage recovery, which is caused by poor heat dissipation. When the voltage fluctuates greatly fluctuating, the module has a greater probability of burning.

Eight, precautions

1. Forbidden heat plugging. When the module is used, first connect the input end GND, VIN output end Vout, GND, and then turn on the power supply supply. After the load is prohibited, the power supply is prohibited.

2. Regarding the use of the EN port, the EN port module is pulled by default, that is, if the capable state needs to be disabled, connect EN to the GND to the shutdown mode, and the module has no output after the EN pulls down.

3. The output of the module cannot be directly connected to the emotional load (such as motor products).

4. Do not reflect the positive and negative pole, and it will burn out.

5. The jump pads selected by the output voltage can only be welded. If you want to switch the output voltage, remove the tin on the tin on the jump pad of the original output voltage to ensure that the two small piles on the jump pad are not connected.Then welding other voltage selection jump pads.6. The default AD "pile is reserved. Customers needed customers calculate the resistance value according to the formula.

7. No anti -inverted irrigation and short -connected protection functions.

8. In order to prevent the client's hand touch the module circuit due to electrostatic and other reasons, the chip is destroyed, so you should try to avoid the module touched the circuit near the chip with your hand when powering.
