Frequently Asked Questions
What control technique does the UC2852D use for power factor correction?
The UC2852D uses current-mode pulse width modulation (PWM) control, which forces the input current to follow the sinusoidal AC line voltage waveform, achieving a high power factor close to unity and reducing total harmonic distortion in the power supply.
What is the operating input voltage range of the UC2852D?
The UC2852D operates with an input voltage from 12.5V minimum to 30V maximum, with a nominal operating voltage of 24V. This range is compatible with standard industry supply rails used in telecom and industrial power systems.
What package is the UC2852D available in?
The UC2852D is housed in an 8-Pin SOIC (Small Outline Integrated Circuit) surface-mount package with JESD-30 code R-PDSO-G8, which is a common and widely supported package footprint for power management ICs in high-volume production.
What types of power supplies benefit most from using the UC2852D?
The UC2852D benefits switch-mode power supplies in desktop PCs, servers, industrial drives, and LED lighting systems where active PFC is required to meet IEC 61000-3-2 harmonic emission standards and improve overall energy efficiency.
