3 Description
The UCC2818A-Q1 device provides all the functions
necessary for active power factor corrected
preregulators. The controller achieves near unity
power factor by shaping the ac input line current
waveform to correspond to that of the ac input line
voltage. Average current mode control maintains
stable, low distortion sinusoidal line current.
Designed in Texas Instrument’s BiCMOS process,
the UCC2818A-Q1 device offers new features such
as lower start-up current, lower power dissipation,
overvoltage protection, a shunt UVLO detect circuitry,
a leading-edge modulation technique to reduce ripple
current in the bulk capacitor and an improved, low?
offset (±2 mV) current amplifier to reduce distortion at light load conditions.
The UCC2818A-Q1 PFC controller is directly pin-for- pin compatible with the UCC2818 devices. Only the
output stage of UCC2818A-Q1 device has been
modified to allow use of a smaller external gate drive
resistor values. For some power supply designs where an adequately high enough gate drive resistor
can not be used, the UCC2818A-Q1 device offers a
more robust output stage at the cost of increasing the
internal gate resistances. The gate drive of the
UC2818A, however, remains strong at ±1.2 A of peak
current capability.
The UCC2818A-Q1 device is intended for
applications with a fixed supply (VCC). It is available in the 16-pin D package.
