Board Features:
- Maximum output current of 3A (2.1A constant current)
- New design: Circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitors have a short life and tantalum capacitors pose and explosion risk. This design uses 3x large solid-state ceramic capacitors (MCC).
- Low ripple profile to protect electronic equipment… 12V to 5V 3A is only 10 mV
- Synchronous rectification with up to 94% efficiency for 12V to 5V @ 1A. Some competitors run at an efficiency of only 60-70%. (The efficiency test removes the voltage drop across the input reverse-polarity protection diodes and fuses).
- Over-voltage protection, input 1.5A fuse, output 5V 300W TVS tube over-voltage clamp protection to protect USB devices.
- Using the latest USB identification circuit for compatibility of IPHONE and most android phones.
- Output voltage indicator (red)Ultra – small size, 26.4 (L) * 15 (W) * 7.4 (H) mm.
- Reverse polarity protection diode on input
