3 Introduction
IP
6566 is a buck converter with integrated synchronous switch, supporting
Supports multiple output fast charging protocols, supports Type C output and USB
Dual-port output SOC IC of PD 2.0/PD3.0(PPS) protocol is for car
On-board charger, fast charging adapter, smart power strip provide complete solution
plan.
IP
6566 supports dual USB Type C USB Type C and
USB A, or dual USB A output, integrated dual-port automatic plug-in and pull-out
Detection function, any one port can support fast charging output when used alone.
When the dual ports are used at the same time, both ports output 5V, and the total power is 5V 3.4 A.
IP
6566 built-in power MOS input voltage range is 8.2 V
to 32 V, the output voltage range is 3V to 12 V. The maximum
20 W output power, can automatically charge according to the recognized fast charging protocol
Adjust output voltage and current. IP 6566 output 5V 3A board end to
The exchange efficiency is as high as 93.8.
IP
The PD output of 6566 has CV/CC characteristics. When the output
When the current is less than the set value, the output is in CV mode and the output voltage is constant;
When the output current is greater than the set value, the output CC mode, the output voltage
reduce .
IP
The output voltage of 6566 has a line compensation function, and the output current increases
After the increase, the output voltage will be increased accordingly to compensate for the impedance of the connecting line.
voltage drop.
IP
6566 has a soft start function to prevent startup shock.
The impact current affects the stability of the input power supply.
IP
6566 has a variety of protection functions, including input overvoltage and undervoltage.
Protection, output over-current, over-voltage, under-voltage, short-circuit protection and other functions.
