PIN DESCRIPTION
Name
Pin
Type
Function
Vcc
5
supply
Positive supply voltage. The DC supply voltage must be higher than the maxi-
mum 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 VCC is 15.2V
Vrefmain
14
analog input
Reference comparison input for main converter regulation loop.
2.5V
±
1.6%
Fbmain
15
analog output
Output for main converter regulation loop (optocoupler)
Vrefaux
13
analog input
Reference comparison input for auxiliary converter regulation loop.
2.5V
±
1.6%
Fbaux
12
analog output
Output for auxiliary converter regulation loop (optocoupler)
IS33
20
analog input
3.3V overcurrent control sense input.
V33
1
analog input
3.3V overvoltage control sense input.
IS5
19
analog input
5V overcurrent control sense input.
V5
2
analog input
5V overvoltage control sense input.
IS12
18
analog input
12V overcurrent control sense input.
V12
3
analog input
12V overvoltage control sense input.
Adj
4
ana 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, VS33 should not be connected.
Tsur
17
program.
analog input
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.
Rem
7
logic input
Remote On/Off logic input for
μ
C, turn off PWM after Trem delay.
Rem = 0 means that the main SMPS is operational.
Trem
8
program.
analog input
Connected to external capacitor to determine Trem (remote control delay) tim-
ing. Trem (on to off) is 8ms typ. Trem (off to on) is 24ms typ.
Crem = 0.1
μ
F
PWM
6
logic output
Output signal to control the primary side of the main SMPS through an
opto-coupler. When PWM is low, the main SMPS is operational.
Tpor
10
program.
analog input
Connected to external capacitor for Power-on-reset timing.
Cpor = 2.2
μ
F
UV
11
analog input
Undervoltage detection, control and detect main AC voltage failure.
PG
9
logic input
Power Good logic output, 0 or 5V. Power Good high (=1) means that the
power is good for operation.
GND
16
supply
Ground or Negative supply voltage.
