Figure 21. Application Schematic
This pin is designed to receive a current that is proportional to the preconverter output
voltage. This information is used for both the regulation and the overvoltage and
undervoltage protections. The current drawn by this pin is internally squared to be used
as oscillator capacitor charge current.
This pin makes available the regulation block output. The capacitor connected between
this pin and ground, adjusts the control bandwidth. It is typically set below 20 Hz to
obtain a nondistorted input current.
The circuit uses an on--time control mode. This on--time is controlled by comparing the
C
This pin is designed to receive a negative voltage signal proportional to the current
flowing through the inductor. This information is generally built using a sense resistor.
The Zero Current Detection prevents any restart as long as the Pin 4 voltage is below
(--60 mV). This pin is also used to perform the peak current limitation. The overcurrent
threshold is programmed by the resistor connected between the pin and the external
current sense resistor.
This pin is designed to receive a synchronization signal. For instance, it enables to
synchronize the PFC preconverter to the associated SMPS. If not used, this pin must
be grounded.
This pin must be connected to the preregulator ground.
The gate drive current capability is suited to drive an IGBT or a power MOSFET.
This pin is the positive supply of the IC. The circuit turns on when V
than 11 V, the operating range after startup being 8.5 V up to 16 V.
