TP5400 1A Lithium Battery Charging Module 5V 1A Step Up Module Micro USB Interface Features: 1. This module is a single-cell lithium-ion battery charger and constant 5V boost controller specifically designed for power banks. 2. The charging section integrates high-precision voltage and charging current regulators, pre-charging, charging status indication, and charge termination functions. 3. The boost circuit uses a VFM switching DC/DC boost converter manufactured with CMOS technology, featuring extremely low no-load current. 4. It has extremely low no-load power consumption, and the boost output drive current capability can reach 1A. It requires no external buttons; it's plug-and-play. 5. The boost input power supply has a current limiting loop that dynamically adjusts the current according to the load and features fast response and overcurrent shutdown functions.

Product Parameters: Input Section: Micro USB charging input: 5V (Charging input voltage range: 5-9V) Maximum charging current: 0.99A Charging battery: 3.7V single-cell lithium-ion battery Charging voltage: 4.2V

Output Section: Output voltage: 5V (when not charging) Note: When charging and discharging simultaneously, the output voltage = input voltage - 0.4V Output current: 1A

Interface: Micro USB PCB size: 45*20mm

Interface Description: 5V IN/VIN: Charging input BATT IN: 3.7V lithium battery 5V OUT/5V: 5V boost output when not charging Note: When charging and discharging simultaneously, the output voltage = input voltage - 0.4V For example: If the charging input voltage is 6V, the output voltage is: 6-0.4=5.6V 3.7V OUT: 3.7V lithium battery output
