Frequently Asked Questions
What control technique does the UCC3817DTRG4 use for power factor correction?
The UCC3817DTRG4 uses average current-mode control with pulse width modulation (PWM) to shape the input current waveform to follow the AC input voltage, achieving near-unity power factor and low harmonic distortion in boost PFC converter designs.
What supply voltage range does the UCC3817DTRG4 require?
The UCC3817DTRG4 requires a supply voltage between 10.3V minimum and 15V maximum, with a nominal operating voltage of 12V, making it compatible with auxiliary power rails commonly available in off-line switch-mode power supplies.
What package is the UCC3817DTRG4 available in?
The UCC3817DTRG4 is available in a 16-pin SOIC package (JESD-30 code R-PDSO-G16), providing a standard small-outline surface-mount footprint that is easy to assemble and widely supported by PCB design tools.
What type of converter topology is the UCC3817DTRG4 designed for?
The UCC3817DTRG4 is specifically designed for boost PFC pre-converter topologies used as the front end in off-line AC-DC power supplies, where it controls the boost inductor current to achieve high power factor while regulating the DC bus voltage.
In what applications is the UCC3817DTRG4 commonly used?
Common applications include power factor correction stages in desktop PC power supplies, server power units, industrial AC-DC converters, uninterruptible power supplies (UPS), and any equipment needing to comply with IEC 61000-3-2 power quality standards.
