Maorui Core into Philips supply chain
Oct 19, 2022| Maorui Core into Philips supply chain
schitec previously disassembled the Philips 30W 1A1C gallium nitride charger, and found that its primary control chip used the core MK2697G, which is a high-frequency QR AC-DC PWM control chip with SOT23-6 minimal package. It supports PPS wide range output and has adaptive multi-mode characteristics. Meet the energy efficiency requirements of PD quick charge under different output voltages.
Maorui MK2697G Vcc withstand 110V, support 9-90V Vcc power supply, without external voltage regulator circuit, reduce the space of the board, more flexible use. The patented driving technology supports direct-drive enhanced GaN power devices, and optimizes SR Vds stress, effectively improving product efficiency and power density.
MK2697G supports 200KHz operating frequency, which can take full advantage of gallium nitride switch, improve efficiency and reduce adapter size. The chip has multiple protection such as output overvoltage, overpower, VCC overvoltage, input overvoltage protection and synchronous rectifier short circuit protection. It is suitable for USB PD charger and high power density power supply applications.
