Description
The device is a current-mode PFC controller operating in Transition Mode (TM). Based on
the core of a standard TM PFC controller, it offers improved performance and additional
functions.
The highly linear multiplier, along with a special correction circuit that reduces crossover
distortion of the mains current, allows wide-range-mains operation with an extremely low
THD even over a large load range.
The output voltage is controlled by means of a voltage-mode error amplifier and a precise
(1.5% @TJ = 25°C) internal voltage reference. The stability of the loop and the transient
response to sudden mains voltage changes are improved by the voltage feedforward
function (1/V2 correction).
Additionally, the IC provides the option for tracking boost operation (where the output
voltage is changed tracking the mains voltage). The device features extremely low
consumption (
≤ 90 µA before start-up and ≤ 5 mA running).
In addition to an effective two-step OVP that handles normal operation overvoltages, the IC
provides also a protection against feedback loop failures or erroneous output voltage
setting.
In the L6563 a protection is added to stop the PFC stage in case the boost inductor
saturates. This function is not included in the L6563A. This is the only difference between
the two part numbers.
An interface with the PWM controller of the DC-DC converter supplied by the PFC pre-
regulator is provided: the purpose is to stop the operation of the converter in case of
anomalous conditions for the PFC stage (feedback loop failure, boost inductor's core
saturation) in the L6563 only and to disable the PFC stage in case of light load for the DC-
DC converter, so as to make it easier to comply with energy saving norms (Blue Angel,
EnergyStar, Energy2000, etc.). The device includes disable functions suitable for remote
ON/OFF control both in systems where the PFC pre-regulator works as a master and in
those where it works as a slave.
The totem-pole output stage, capable of 600 mA source and 800 mA sink current, is suitable
to drive high current MOSFETs or IGBTs. This, combined with the other features and the
possibility to operate with the proprietary Fixed-Off-Time control, makes the device an
excellent low-cost solution for EN61000-3-2 compliant SMPS in excess of 350W.
