onsemi FAN6500xx Switching Controllers
onsemi FAN6500xx Switching Controllers are wide input voltage highly efficient synchronous buck regulators with integrated high-side and low-side power MOSFETs. These controllers incorporate a fixed frequency voltage mode PWM controller with 4.5V-65V wide voltage range and can handle continuous currents up to 6A, 8A, and 10A. The FAN6500xx controllers include a 0.67% accurate reference voltage to achieve tight regulation. The controller switching frequency can be configured between 100kHz to 1MHz.
The FAN6500xx controllers use onsemi’s high-performance PowerTrench® MOSFETs that reduce ringing in switching applications. These controllers offer protection features like overcurrent protection, thermal shutdown, under-voltage lockout, overvoltage protection, under-voltage protection, and short-circuit protection. Typical applications include high-voltage POL modules, telecommunications, networking, and industrial equipment.
