ON Semiconductor DAP013C Power Factor Correction Controller

The ON Semiconductor DAP013C is a sophisticated and highly integrated Power Factor Correction (PFC) controller designed for use in various applications that require efficient power supply solutions. This advanced controller is engineered to provide a low-cost, low-component count, and high-performance PFC function that significantly enhances the power factor and reduces total harmonic distortion (THD).

The DAP013C operates in Continuous Conduction Mode (CCM), which ensures stable and efficient operation even under varying load conditions. This mode of operation is ideal for applications that demand a high power factor and tight regulation, such as in switch-mode power supplies (SMPS) for televisions, monitors, servers, and telecommunication equipment.

Featuring a built-in high-voltage startup circuit, the DAP013C is capable of quickly and efficiently initiating the power conversion process. This allows the PFC controller to minimize standby power consumption, making it an environmentally friendly choice for energy-conscious designs. Additionally, the device includes over-voltage protection (OVP), under-voltage lockout (UVLO), and over-current protection (OCP) to ensure the safety and reliability of the power supply.

The DAP013C controller is designed for flexibility and ease of use, with an adjustable output voltage that enables designers to tailor the power supply to specific application requirements. Its internal clamping circuit limits the gate voltage of the external MOSFET, protecting the MOSFET and enhancing system reliability. The device also features a disable function that can be used to turn off the PFC controller, further reducing power consumption when the PFC function is not required.

In summary, the ON Semiconductor DAP013C is a versatile and efficient solution for power factor correction in a wide range of AC-DC power conversion applications. With its robust feature set and high level of integration, this PFC controller is a compelling choice for designers looking to improve the performance and energy efficiency of their power supply systems.
