SG6105D
20-Pin DIP
PIN DESCRIPTIONS
Name
Pin
Type
Function
VCC
20
Supply
Supply voltage. 4.5V ~ 5.5V. It is connected to 5V-standby.
Power Good logic output, 0 or 1 (open-collector). PG = 1 means that the power is good for operation.
The PG delay is 300 msec.
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.
V12
7
Analog input
12V over-voltage/under-voltage control sense 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.
Remote On/Off logic input for CPU or controller. Turn on/off the PWM Output after the 7.5 msec / 26
msec delay.
PSON = 0 means that the main SMPS is operational.
PSON =1 means that the main SMPS is off and the latch is reset.
NVP
6
Analog input
The protection input for negative output, such as –12V and/or –5V. Trip voltage = 2.1V.
UVAC
5
Analog input
AC fail detection, detect main AC voltage under-voltage and/or failure.
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.
The soft-start. It is settable through external capacitor. The current source output at this pin is 8uA and
the voltage is clamped at 2.5V.
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%.
FB1
14
Analog output
Output for first converter regulation loop.
VREF1
13
Analog input
Reference comparison input for first converter regulation loop. 2.5V.
FB2
11
Analog output
Output for second converter regulation loop.
VREF2
12
Analog input
Reference comparison input for second converter regulation loop. 2.5V.
Program.
Analog input
RI = 75k ohms.
GND
15
Supply
Ground.
