Description:
TP5000 3.2V for Lifepo4 Charging Module Lithium ion Battery Charge Module 4.2V 1A USB for Lipo Battery Charging Board
The charging current is 1A, and the charging is maintained at 1A during the whole process of constant current. No additional heat dissipation is required, which reduces the influence of heat on the charging current. Reduce charging time. Optional ordinary lithium ion lithium polymer battery or lithium iron phosphate battery, only need a for jumper to change the setting.
Feature:
Input voltage 4.5-9V
Output voltage 4.2V/3.6V plus or minus %(the circuit board defaults to 4.2V lithium ion battery)
Output current: default 1A
Copper tape 5A high current and small size inductor, fully closed , low loss and low interference!
Single-sided machine mounting, the overall 4mm ultra-thin, small area, good heat dissipation, exposed copper on the back for easy installation and heat sink
Based on the DC-DC step-down, the efficiency is much higher than that of the linear charging circuit, and the heat is much smaller. The charging current is 1A, but the input current is only about 0.7A.
Optional lithium iron phosphate battery or ordinary lithium ion/lithium polymer battery, only a for jumper can be set
Small size, the size of a cent coin, 1A charging without additional heat dissipation
With overheating for protection, overheating will automatically reduce the current to prevent burnout
Full-page high-precision resistors, the most stable temperature characteristics of 1210 precious metal multilayer ceramic capacitors for X7R
Fully automatic stop, dual-color charging status indicator
Parameters:
Size: 21.5mm*14.5mm*4.2mm, ultra-thin and ultra-small, cent coin size, single-sided reflow soldering
Input: 4.5-9V(recommended not to exceed 7V)
Output voltage: 4.2V/3.6V plus or minus % for jumper selection
Output current: 1A by default, heat dissipation is required for more than .5A
4 terminal blocks, 2 inputs, 2 batteries, and a soldering position for in-line LEDs
Instructions:
A red-green or red-green is included with the circuit, you need to solder it to the circuit by yourself, as shown in the baby picture, the longest leg is in the middle, the longest leg is close to the chip, and the shortest leg is close to the outside.
The power terminal is connected to a 4.5-7V power supply, the current should be greater than the charging current, and the green light is on at this time
The battery terminal is connected to a lithium battery or a lithium iron phosphate battery. If the battery needs to be charged, it will turn red
If you need to adjust the current, please modify the current you need in the current sampling resistor. Sampling voltage 0.1V, current =0./resistance value
The circuit has been soldered with a 0. ohm resistor and there is a space
Package:
*Charging Module
Note:
. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.
2. Please allow slight manual measurement deviation for the data.
