DC-DC Buck 4 USB Charger Module 8A

Description

• The 4-channel independent dedicated charging management IC can effectively support the maximum current charging of various mobile phones, and the charging speed is fast, safe and reliable.
• The charging recognition IC is compatible with Apple’s full range of products (backside recognize IC), and most mobile phones can achieve the fastest charging speed.
• Support 4 channels of USB for 2A current charging at the same time, the current is large and the charging is fast, and the total output current can reach 8A.
• The input use MOS tube to protect reserved wrong connection, and maximize conversion efficiency and reduce loss.
• The output is protected against overvoltage to protect the phone.
• The 8-35V ultra-wide input voltage and 12V 24V are perfectly supported.
• The synchronous rectification scheme can effectively reduce the heat generation and improve the efficiency, and the efficiency can reach up to 96%.
• The industry’s advanced flat line high current inductance, large current and small heat generation, high conversion efficiency.
• 4 high-quality chip capacitors, and then increase the capacity of MLCC capacitors, the output ripple is lower, and the interference is smaller.
• High-quality double-layer gold-plated USB port, the life is twice that of ordinary USB.
• The default delivery is about 5.2V output voltage.
• Support Apple and Samsung fast charge protocol.
