Description
Sense Input. Represents the input for the Power-OK behavior. This input can be used to supervise
the input or the output voltage via a resistor divider. If connected to GND the POK output is related to
V OUT .
Feedback Pin. Feedback input to the g m error amplifier. Connect a resistor divider tap to this pin. The
output voltage can be adjusted from 1.8 to 3.3V by: V OUT = 0.8V[1 + (R 1 /R 2 )]
If the fixed output voltage version is used, connect this pin to VOUT.
Active-High Enable Input. A logic LOW reduces the supply current to < 1 A.
Connect to pin VIN for normal operation.
Power-OK Output. Active-High, open-drain output indicates an out-of-regulation condition. Connect
a 100k ? pull-up resistor to pin OUT for logic levels. Leave this pin unconnected if the Power-OK
feature is not used.
Low Level: V OUT is out of Regulation
High Level: V OUT is within Regulation
Signal and Power Ground . Provide a short, direct PCB path between this pin and the negative side
of the output capacitor(s).
Switch Pin. Connect an inductor between this pin and V IN . Keep the PCB trace lengths as short and
wide as is practical to reduce EMI and voltage overshoot. If the inductor current falls to zero, or pin
EN is low, an internal 100 ? anti-ringing switch is connected from this pin to V IN to minimize EMI.
Note: An optional Schottky diode can be connected between this pin and V OUT .
Output Voltage. Bias is derived from V OUT when V OUT exceeds V IN . PCB trace length from V OUT
to the output filter capacitor(s) should be as short and wide as is practical.
Input Voltage. The AS1330 gets its start-up bias from V IN unless V OUT exceeds V IN , in which case
the bias is derived from V OUT . Thus, once started, operation is completely independent from V IN .
Operation is only limited by the output power level and the internal series resistance of the supply.
Exposed Pad. The exposed pad must be connected to GND. Ensure a good connection to the PCB
to achieve optimal thermal performance.
