OP
SIN_REF
This pin generates a PWM signal with the sinusoidal duty cycle. This PWM signal
must be filtered in order to have the current sinusoidal reference that is synchronized
with input voltage mains.
20
O
FAN
It generates a CMOS/TTL signal that is low until the PFC output power is below a
threshold defined during device customization.
21
O
RELAY
It generates a CMOS/TTL signal. This signal becomes high after a settable time
defined during device customization. It is useful to perform the inrush current limiter
function.
22
O
PTX
Programming data transmit
23
I
PRX
Programming data receive
24
AI
OUT_PI[3]
Positive input of the internal analog comparator 3. It receives the out of the analog PI
current.
25
AI
OUT_PI[2]
Positive input of the internal analog comparator 3. It receives the out of the analog PI
current.
26
AI
TRIANG
REF
Negative input analog comparators 3 and 2. It receives the voltage triangular
waveform.
27
AI
OCP[0]
Input overcurrent protection
28
AI
OCP[1]
Inductor overcurrent protection
29
PS
VDDA
Analog supply voltage
30
PS
VSSA
Analog ground
31
MI
VIN
This pin measures the RMS input voltage.
32
MI
TEMP
This pin measures the ambient board temperature. This measurement is performed
using the STLM20 device, which gives an output voltage proportional to temperature.
33
MI
IOUT
This pin measures the PFC output current.
34
MI
VOUT
This pin measures the PFC output voltage.
35
RI
RI[1]
Reserved. This pin must be pulled down by means a 10 k
 resistor.
36
RI
RI[2]
Reserved. This pin must be pulled down by means a 10 k
 resistor.
37
RI
RI[3]
Reserved. This pin must be pulled down by means a 10 k
 resistor.
38
RI
RI[4]
Reserved. This pin must be pulled down by means a 10 k
 resistor.
