This 1 MHz DC-DC Step-Up Boost IC Can be used in the application, for example, getting stable 5V from 3V battery. The DC-DC Boost Converter Circuit is designed using the DC-DC Boost Converter FP6291 IC. The LEDs connected with it indicates the charging status. This IC handles the Battery charging operation by processing the 5V DC input supply received through the Micro USB socket.

Its SOP package and low external component count make the TP4056 ideally suited for portable applications. TP4056 is a complete constant-current/constant-voltage linear charger for single-cell Lithium-ion batteries.
The battery charger circuit is designed around a dedicated lithium-ion battery charger TP4056 IC. The complete working of the circuit can also be found in the video at the bottom of this page. Here in this circuit, we used a USB Type-A Female Connector on the Booster side and a Micro USB 2.0 B type 5 Pin Connector on the Charger side. The Booster part is used to boost the battery voltage from 3.7v to 4.5v-6v. This circuit has two main parts, one is the battery charging circuit, and the second is DC to DC boost converter part. The circuit diagram for 18650 Lithium Battery Charger & Booster Module is given above. In the following sections of the article we have covered in details the complete procedure to design, order and assemble the PCB boards for this lithium battery charger circuit. Here we have used PCBWay to provide the PCB boards for this project. If you are completely new to lithium batteries and charger circuits, do check out the introduction to lithium batteries and Lithium battery charger circuit to get an idea before proceeding with this circuit. Throughout the tutorial, we will discuss the circuit diagram, how I designed the PCB, how I ordered it, and what kind of problems occurred while soldering the components and testing the circuit. The charging current of our module is set to 1A and the output current is also set to 1A at 5V, however, it can also be easily modified to provide up to 2.5A if required and supported by the battery. The module can safely charge a lithium battery and boost its output voltage to a regulated 5V which can be used power most of our development boards like Arduino, NodeMcu, etc. A battery module like this will be very useful when powering our electronic projects with lithium batteries.
In this tutorial, we are going to build a Lithium Battery Charger & Booster Module by combining the TP4056 Li-Ion Battery Charger IC and FP6291 Boost Converter IC for a single-cell Lithium battery.
