Transition mode boost Power Factor Correction controller

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

The device uses ACM-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) and brown-in/out.

NEX83288 is available in SO8 package. Table 1. Device information Part number Package Body size NEX83288 SO8 4.9 mm x 3.9 mm x 1.75 mm Figure 1. Typical application
