Name
Pin
Type
Function
PSON
1
Logic Input
Remote on/off logic input for
CPU or controller. Turn on/off the PWM output after the 7.5ms
/ 26ms delay.
PSON = 0, the main SMPS is operational.
PSON =1, the main SMPS is off and the latch is reset.
V33
2
Analog Input
3.3V over-voltage/under-voltage control sense input.
V5
3
Analog Input
5V over-voltage/under-voltage control sense input.
OPP
4
Analog Input
Over-power sense input. This pin is connected to driver transformer or the Output of current
transformer. When not in use, this pin should be grounded.
UVAC
5
Analog Input
AC fail detection, detect main AC voltage under-voltage and/or failure.
NVP
6
Analog Input
The protection input for negative Output, such as –12V and/or –5V. Trip voltage = 2.1V.
V12
7
Analog Input
12V over-voltage/under-voltage control sense input.
OP1/OP2
9/8
Analog Output
The totem-pole Output drivers of push-pull PWM. The Output are enabled (low) only when
the NAND gate inputs are high. The maximum duty cycle on an Output (OP1 or OP2) is
46%.
PG
10
Logic Output
Power-good logic output, 0 or 1 (open-collector). PG = 1, the power is good for operation.
The PG delay is 300ms.
FB2
11
Analog Output
Output for second converter regulation loop.
VREF2
12
Analog Input
Reference comparison input for second converter regulation loop, 2.5V.
VREF1
13
Analog Input
Reference comparison input for first converter regulation loop, 2.5V.
FB1
14
Analog Output
Output for first converter regulation loop.
GND
15
Supply
Ground.
COMP
16
Analog Output
Error amplifier Output and the input of the PWM comparator.
IN
17
Analog Input
The negative input of error amplifier. The positive input of error amplifier is a 2.5V reference
voltage.
SS
18
Analog Input
The soft-start, settable through an external capacitor. The current source output at this pin
is 8μA and the voltage is clamped at 2.5V.
RI
19
Program Analog
Input
Connected to external resistor for the reference setting. R
I
= 75k
Ω.
VCC
20
Supply
Supply voltage. 4.5V ~ 5.5V connected to 5V-standby.
