Transition mode boost Power Factor Correction controller

NEX83288 is a Power Factor Correction (PFC) controller. It supports transition mode (CrM/DCM) operations.

The device uses average current mode based VOT-control to achieve high power factor and low-current total harmonic distortion (THD) over a wide line voltage. The device features a very low supply current in burst mode. This allows the device to achieve low standby power loss.

The switching frequency near the line voltage zero cross region is reduced by the control method. It improves efficiency.

NEX83288 features overvoltage protection (OVP), cycle-by-cycle (CBC) current limit, open-loop protection (OLP), overtemperature protection (OTP), brown-in and brown-out.

NEX83288 is available in SO8 package.

交互式数据手册

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
