Type-C USB 5V 2A Step-Up Power Boost Converter Module Lithium Battery Charging Protection Board Module 4.2V/4.35V 10pcs

Brand: Teyleten Robot

• Input voltage range: 5~5.5V
• Charge cut-off voltage: (4.2V/4.35V) ±0.5%
• Charge current: 2.4A ±5%
• Boost output voltage: 5V~5.15V (with wire loss compensation)
• Boost output current: 2A
• Boost conversion efficiency: 92.5% (3.6V input, 5V 2A output)
• Battery-side quiescent current: <30μA
• Boost output voltage ripple: 100mV

Details: 1. Output will shut off when load current remains below 50mA. 2. Supports external button connection. Connect button to K point and output negative terminal. A short press activates power display and enables 5V output. Two consecutive short presses deactivate power display and disables 5V output. 3. Charging cycle automatically terminates when charging current drops to 100mA after reaching final float voltage. 4. The charging cycle will restart when the battery voltage drops below 4.1V. 5. When the battery voltage falls below 2.8V, a pre-charge at 180mA will initiate. 6. A USB-A female port soldering location is provided on the product's rear for manual installation. 7. Supports simultaneous charging and discharging.
