Description
TPS61088 2.7V to 5V 9V 12V Battery Voltage Boost Circuit DC to DC Step Up Boost Converter Voltage Step Up Stabilizer
Product Description
This module adopts TPS61088 power chip solution, with stable performance, small ripple, 10A switching current capability, and switching frequency of about 1MHZ. The module provides two working modes, PWM and PFM, which can be adjusted by the user (default PFM low power consumption mode is shipped) , On-board high-quality large capacitors (adjustable version) and flat copper wire inductors, the high-quality components used further improve the performance and stability of the module. The module still has the stability unmatched by most other booster modules in the case of high output power. It is a must for users to use multiple lithium batteries in parallel to power the booster and apply it to the high current output of 5V voltage 4A/5A. It is a good choice, the same step-up to 9V/12V voltage is not a problem, the output power Highest can reach 30w, 9v, 12V voltage output, when the output is larger current, the user only needs to do a good job of cooling to get a good band load output ripple. Unless otherwise specified, the following parameters are tested in PWM mode (recommended working mode).

Jumper soldering
Short circuit enables the corresponding voltage, if all jumper pads are not shorted Then use the ADJ resistor to adjust the
voltage, three pads and ADJ resistor can only choose one way to work
The PWM shorting pad on the side of the output terminal is shorted for PWM mode, disconnected for PFM mode, and the default is PFM mode, which can be adjusted by the user. For the fixed voltage version, the default is PFM mode, you can solder 0Q resistors on the PWM pad or short-circuit the two pads in other ways to adjust to PWM mode.

About output

1. The module is a step-up module, so the output voltage regulated by the module needs to be higher than the input voltage After testing, it is recommended that the output voltage be more than 2V higher than the input voltage, otherwise it is easy to cause the output voltage to be higher than the set value. 2. The MAX switching current of the module is 10A, and the user is required to leave room to use it within 9A use. 3. The output current is determined by the input parameters, the input current shall not exceed 9A, the efficiency 70% (leaving room) for calculation, the following formula is used to calculate the output MAX current value of the module: lout=Vin*6.3/Vout. 4. When the input voltage of the module is too low, the output power cannot be fully utilized. It is especially obvious when the power supply is below, and users who need larger power output should pay attention to it.

5. For the fixed voltage output version, the PWM mode output voltage will be low, but the basic This is not affected, the preliminary test of the multimeter has a deviation of about 0.1V. 6. The relationship between ADJ resistance and output voltage of the fixed voltage output version is as follows Rn,=(Vor-Vas)*56000/VaEs PWM mode: V = 1.204(min:1.186 max:1.222)PFM mode: Ves = 1.212 The following are the ripple parameters measured by our company using high-quality low-ripple adjustable switching power supply input. Due to the difference in input power supply, load and measurement methods, the user's measured results may be different from the following table.
