Wide power supply high-frequency QR PWM controller MK2697

About Wide power supply high-frequency QR PWM controller MK2697

MK2697 is a QR PWM optimized for PD/fast charging applications

Controller. Its wide VCC operating voltage range (9V-90V)

It can cover the output range of PD/PPS from 3.3V-23V

Surrounding without the need for additional windings or linear step-down circuits.

Regarding energy efficiency requirements, there are multiple different options for PD/fast charging

Output voltage, therefore adaptive multi-mode is adopted. It is not

Adjust and work on DCM/QR under the same load and different outputs.

When under light load, it will work in burst mode to improve efficiency.

MK2697 provides comprehensive protection functions with outputs

OVP, OPP, VCC OVP, BROWN-IN/OUT,

It also provides secondary SR short circuit protection and PIN pin

OPEN/SHORT protection, etc.
