The FAN6863SWRTY from ON Semiconductor is a cutting-edge PWM (Pulse Width Modulation) controller designed for high-performance switch-mode power supplies. This highly integrated device offers a suite of features aimed at achieving low power consumption and high efficiency, making it an ideal choice for a variety of applications, including battery chargers, adapters, and standby power systems.

The FAN6863SWRTY incorporates ON Semiconductor's innovative green-mode function, which reduces standby power consumption to below 75mW. This feature allows power supplies to meet stringent energy efficiency standards. Furthermore, the green-mode function ensures that the PWM frequency decreases linearly with the load, minimizing audible noise and improving overall efficiency.

This PWM controller supports a wide range of input voltages, making it versatile for global applications. It is equipped with various protection features, such as overload protection (OLP), over-voltage protection (OVP), and under-voltage lockout (UVLO), ensuring the safety and reliability of the power supply under abnormal conditions.

The FAN6863SWRTY employs a frequency hopping technique that helps to reduce EMI emission, a critical factor for passing regulatory tests. This feature, along with its built-in soft-start capability, ensures a smooth startup process without triggering over-current protection.

For design flexibility, the device also includes an internal high-voltage startup circuit that enables quick and efficient startup, reducing the need for external components. Its built-in leading-edge blanking (LEB) on the current sense input removes the requirement for an external noise suppression circuit, simplifying the design and reducing BOM cost.

ON Semiconductor's FAN6863SWRTY is available in a compact SOP-8 package, making it suitable for space-constrained applications. Its high level of integration and energy-saving features make it a smart choice for designers looking to create efficient, reliable, and cost-effective power solutions.
