The LNK6767K is a fully integrated off-line switcher IC with burst-mode and valley-fill flyback topology designed with multiple protection features. It is designed for applications such as adapters and notebook computers that require power with wide input range and high efficiency. This IC integrates the control part and power part, making it a perfect solution for traditional offline adapters.

The LNK6767K is an AC/DC converter with flyback topology and integrates an internal switch, controller, PWM, and high-voltage startup circuit to minimize the system cost and size. This IC supports an ultra-wide range of input voltage up to 265VAC, and its operating frequency ranging from 40 to 450KHz allows the system to operate in either Low Standby Power (LSP) or high performance mode. The power saving mode can reach up to 4.5W under 265VAC input conditions.

The LNK6767K\'s internal power switch is capable of working in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The CCM mode is suitable for high power adapters, while the DCM mode is more suitable for applications with low power requirements. It also includes internal circuitry for voltage-mode control, enabling the designer to easily design high efficiency power rediolution without any external compensation components.

In addition, the LNK6767K provides multiple protection features, including over current protection (OCP), over voltage protection (OVP), over temperature protection (OTP) and short circuit protection (SCP) to ensure the system’s reliability. The OVP feature can detect any output voltage exceeding its safe range, while OCP and SCP features can shutdown the system when current or voltage exceed its threshold.

To sum up, the LNK6767K provides a perfect solution for offline switchers and AC/DC converters. Its wide input voltage range, high efficiency, and complete protection features make it an ideal choice for applications such as adapters and notebook computers.
