Description

Sense Input. Represents the input for the PowerꢀOK 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

VOUT.

SENSE

Feedback Pin. Feedback input to the gm error amplifier. Connect a resistor divider tap to this pin. The

output voltage can be adjusted from 1.8 to 3.3V by: VOUT = 0.8V[1 + (R1/R2)]

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 < 1ꢁA.

Connect to pin VIN for normal operation.

Power-OK Output. ActiveꢀHigh, openꢀdrain output indicates an outꢀofꢀregulation condition. Connect

a 100kΩ pullꢀup resistor to pin OUT for logic levels. Leave this pin unconnected if the PowerꢀOK

feature is not used.

POK

Low Level: VOUT is out of Regulation

High Level: VOUT 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).

GND

Switch Pin. Connect an inductor between this pin and VIN. 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 100Ω antiꢀringing switch is connected from this pin to VIN to minimize EMI.

Note: An optional Schottky diode can be connected between this pin and VOUT.

Output Voltage. Bias is derived from VOUT when VOUT exceeds VIN. PCB trace length from VOUT

to the output filter capacitor(s) should be as short and wide as is practical.

Input Voltage. The AS1330 gets its startꢀup bias from VIN unless VOUT exceeds VIN, in which case

the bias is derived from VOUT. Thus, once started, operation is completely independent from VIN.

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.
