TP5000 1A Lithium Iron Phosphate (LiFePO4) & Li-ion Battery Charger Module – 3.6V/4.2V Switch-Mode Charging Board in Pakistan

Overview

When your DIY electronics projects or portable solar systems rely on safe, long-life Lithium Iron Phosphate (LiFePO4) or standard Li-ion cells, finding an efficient charger that doesn’t overheat is essential. The TP5000 Lithium Battery Charger Module is a high-efficiency switch-mode power management board built around the robust TP5000 IC. Unlike older linear chargers (such as the TP4056), this buck-converter based module operates with high conversion efficiency and significantly reduced thermal dissipation, making it ideal for enclosed project boxes and continuous-duty applications.

Key Features

• Dual Chemistry Support: Easily configurable via an onboard jumper/solder pad to support both 3.6V/3.2V LiFePO4 cells and standard 4.2V/3.7V Lithium-ion batteries.

• High-Efficiency Switch-Mode Design: Advanced buck topology minimizes heat output compared to traditional linear charging solutions.

• Adjustable 1A Charging Current: Delivers a reliable 1A max default charge rate, which can be scaled via sense resistor modifications.

• Comprehensive Protection: Features built-in input under-voltage, over-temperature, and short-circuit safeguards for secure operation.

Technical Specifications

Common Applications

• LiFePO4 Solar Battery Systems: Efficiently step down minor solar panel voltages to safely top up 3.2V energy storage cells.

• Portable Instrumentation & IoT: Custom power management boards for field sensors running on robust iron-phosphate chemistry.

• DIY Li-ion / LiPo Chargers: Versatile bench charger upgrade replacing older, high-heat linear regulator chips.

• Note to customers: Check and configure the board’s internal solder jumper for 3.6V (LiFePO4) mode before connecting your iron-phosphate battery!
