FUNCTION
3.3 V/12V Source
DESCRIPTION
Connect to source of associated external N-Channel MOSFET switch to sense output
voltage.

3V/12VG
3.3V/12V Gate
Connect to the gate of associated N-Channel MOSFET switch. A capacitor from this node
to ground sets the turn-on ramp. At turn-on this capacitor will be charged to 17.4V by a 10 μ A
current source when in 5v/12V mode of operation, otherwise capacitor will be charged to
11.4V. A small resistor (10 - 200 ? ) should be placed in series with the gate capacitor to
ground to prevent current oscillations.

Invokes 3.3V operation
Connect to 12V supply. This can be either connected directly to the +12V rail supplying the
load voltage or to a dedicated V DD +12V supply. If the former is chosen special attention to
V DD decoupling must be paid.
PWRON1 and PWRON2 are used to turn-on and reset the chip. Both outputs turn-on when
either pin is driven low. After a current limit time out, the chip is reset by the rising edge of a
3.3V control operation in preference to +12V control. By tying pin 4 to pin 3 the charge pump

5V Gate
Connect to the gate of the external 5V N-Channel MOSFET. A capacitor from this node to
ground sets the turn-on ramp. At turn-on this capacitor will be charged to 11.4V by a 10 μ A
current source. A small resistor (10 - 200 ? ) should be placed in series with the gate
capacitor to ground to prevent current oscillations.

5VS
5V Source
Connect to the source side of 5V external N-Channel MOSFET switch to sense output
voltage.

5VISEN
5V Current Sense
Connect to the load side of the 5V sense resistor to measure the voltage drop across this
resistor between 5VS and 5VISEN pins.

PGOOD
Power Good indicator
Indicates that all output voltages are within specification. PGOOD is driven by an open drain
N-Channel MOSFET. It is pulled low when any output is not within specification.

C TIM
Current Limit Timing
Capacitor
Connect a capacitor from this pin to ground. This capacitor controls the time between the
onset of current limit and chip shutdown (current limit time-out). The duration of current limit
time-out (in seconds) = 200k ? x C TIM (Farads).

3.3V/12V Current Sense
Connect a 0.1 μ F capacitor between this pin and V DD (pin3). Directly connect this pin to V DD
when in 3.3V control mode.
A resistor connected between this pin and ground determines the current level at which
current limit is activated. This current is determined by the ratio of the R ILIM resistor to the
sense resistor (R SENSE ). The current at current limit onset is equal to 10 μ A x (R ILIM /
R SENSE ).
Connect to the load side of sense resistor to measure the voltage drop across this resistor.
