Pin Definitions
Pin #
Name
Description
1
IEA
Output of PFC Current Amplifier
. The signal from this pin is compared with an internal
sawtooth to determine the pulse width for PFC gate drive.
2
IAC
Input AC Current
. For normal operation, this input provides current reference for the multiplier.
The suggested maximum IAC is 100A.
3
ISENSE
PFC Current Sense
. The non-inverting input of the PFC current amplifier and the output of
multiplier and PFC ILIMIT comparator.
4
VRMS
Line-Voltage Detection
. The pin is used for the PFC multiplier.
5
SS
PWM Soft-Start
. During startup, the SS pin charges an external capacitor with a 10A
constant current source. The voltage on FBPWM is clamped by SS during startup. If a
protection condition occurs and/or PWM is disabled, the SS pin is quickly discharged.
6
FBPWM
PWM Feedback Input
. The control input for voltage-loop feedback of PWM stage.
7
RT/CT
Oscillator RC Timing Connection
. Oscillator timing node; timing set by RT and CT.
8
RAMP
PWM RAMP Input
. In current mode, this pin functions as the current-sense input; when in
voltage mode, it is the feedforward sense input from PFC output 380V (feedforward ramp).
9
ILIMIT
Peak Current Limit Setting for PWM
. The peak current limits setting for PWM.
10
GND
Ground
.
11
OPWM
PWM Gate Drive
. The totem-pole output drive for PWM MOSFET. This pin is internally
clamped under 19V to protect the MOSFET.
12
OPFC
PFC Gate Drive
. The totem-pole output drive for PFC MOSFET. This pin is internally clamped
under 15V to protect the MOSFET.
13
VDD
Supply
. The power supply pin. The threshold voltages for startup and turn-off are 11V and
9.3V, respectively. The operating current is lower than 10mA.
14
VREF
Reference Voltage
. Buffered output for the internal 7.5V reference.
15
FBPFC
Voltage Feedback Input for PFC
. The feedback input for PFC voltage loop. The inverting
input of PFC error amplifier. This pin is connected to the PFC output through a divider network.
16
VEA
Output of PFC Voltage Amplifier
. The error amplifier output for PFC voltage feedback loop.
A compensation network is connected between this pin and ground.
