IP6557 is an integrated buck-boost controller and path
NMOS control function, supports QC2.0/QC3.0/QC3+/
QC4+/QC5/FCP/HSCP/AFC/MTK/UFCS, and
USB-C interface PD3.1/PPS/ERP28V output fast charging protocol
SOC provides a complete power solution for car chargers.
IP6557’s high integration and rich functions require only one inductor
And power MOSFET can realize the voltage-boost and buck-function
Fast charging solution can effectively reduce the size of the overall solution and reduce BOM
cost.
IP6557 integrated buck-boost controller provides maximum
140W (28V5A) power output, supports NTC board-level temperature detection
The output power can be intelligently adjusted according to the temperature.
IP6557 has built-in 14-bit ADC to accurately measure input and output
voltage and current, and the voltage of IO.
The fast charge output of IP6557 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.
IP6557 integrates multiple protection functions, including input overvoltage, undervoltage
Voltage protection, output overvoltage, undervoltage, overcurrent, short circuit protection, overtemperature
Protection and other functions.
IP6557 is packaged in QFN40 (5mm*5mm).
