TP5000 3.2V Battery Charging Module Lithium ion 4.2V 1A USB Charging Board

TP5000 3.2V Lifepo4 Charging Module Lithium ion Battery Charge Module 4.2V 1A USB 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 magnetic, 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 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 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
