V
CC
Pin
5
Type
supply
Function
Positive supply voltage. The DC supply voltage must be higher than
the maximum voltage applied on the 3.3, 5, 12V inputs (Is3.3, Is5,
Is12) plus 2V.
For example, if 13.2V is present on the Is12 input, the minimum
required value on V
CC
is 15.2V
Reference comparison input for main converter regulation loop.
2.5V +-1.6%
Output for main converter regulation loop (optocoupler)
Reference comparison input for auxiliary converter regulation loop.
2.5V +-1.6%
Output for auxiliary converter regulation loop (optocoupler)
3.3V overcurrent control sense input.
3.3V overvoltage control sense input.
5V overcurrent control sense input.
5V overvoltage control sense input.
12V overcurrent control sense input.
12V overvoltage control sense input.
Adjustment pin for 3.3V OVP. This pin is to be used for an OVP other
than 3.3V (eg for
μ
C power supply = 2.7V). When not in use, this pin
should be grounded. When in use, V
S33
should not be connected.
Overcurrent blank-out time 20 to 30ms settable through external RC.
The voltage at this pin is clamped at typically 5V. Trip voltage = 1.25V.
Remote On/Off logic input for
μ
C, turn off PWM after Trem delay.
Rem = 0 means that the main SMPS is operational.
Connected to external capacitor to determine Trem (remote control
delay) timing. Trem (on to off) is 8ms typ. Trem (off to on) is 24ms typ.
Crem = 0.1
μ
F
Output signal to control the primary side of the main SMPS through
an opto-coupler. When PWM is low, the main SMPS is operational.
Connected to external capacitor for Power-on-reset timing.
Cpor = 2.2
μ
F
Undervoltage detection, control and detect main AC voltage failure.
Power Good logic output, 0 or 5V. Power Good high (=1) means that
the power is good for operation.
Ground or Negative supply voltage.
