Product Usage
The L4984D is a dedicated power factor correction (PFC) controller manufactured by STMicroelectronics that is typically used in applications requiring high efficiency and low harmonic distortion in the power conversion process. It can be found in a variety of power supply circuits, including:
Switched Mode Power Supplies (SMPS):
AC-DC Converters:
Lighting Applications:
Power Adapters and Chargers:
UPS (Uninterruptible Power Supplies):
Telecommunications Equipment:
The L4984D PFC controller improves overall power supply efficiency, reduces electromagnetic interference (EMI), and ensures compliance with power quality standards by controlling and shaping the input current. It typically features Continuous Conduction Mode (CCM) operation for high power applications and includes protections such as overvoltage, overcurrent, and thermal shut-down.
In summary, any circuit requiring active power factor correction to meet regulatory standards and achieve high efficiency can benefit from using the L4984D.
