Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switch node output pin connected to the SW side of the external inductor, with a normal voltage swing from ground to PVIN. |
| 2 | SW | output | Switch node output pin connected to the SW side of the external inductor, with a normal voltage swing from ground to PVIN. |
| 3 | PGND | power_in | Power ground pin to which the negative terminals of the input bypass and output capacitors should be tied with a low impedance connection. |
| 4 | PGND | power_in | Power ground pin to which the negative terminals of the input bypass and output capacitors should be tied with a low impedance connection. |
| 5 | BOOST | power_out | Boosted floating driver supply pin whose normal swing ranges from a diode drop below INTVCC up to PVIN plus INTVCC, with the bootstrap capacitor connected between it and SW. |
| 6 | INTVCC | power_out | Internal 3.3V regulator output that should be decoupled to PGND with a low ESR ceramic capacitor of 1µF or more. |
| 7 | VON | input | On-time voltage input that sets the on-time comparator trip point, making on-time proportional to VOUT when VOUT is 6V or less, with a normal pin impedance of 180kΩ. |
| 8 | RT | passive | Oscillator frequency program pin where an external resistor between 80k and 400k to SGND sets switching from 800kHz to 4MHz, defaulting to 2MHz when tied to INTVCC. |
| 9 | FB | input | Output voltage feedback input to the error amplifier, which compares the feedback voltage to the internal 0.6V reference. |
| 10 | ITH | passive | Error amplifier output and switching regulator compensation pin, which should be connected to INTVCC to use the default internal compensation. |
| 11 | TRACK | input | Output voltage tracking and soft-start input where forcing a voltage below 0.6V overrides the internal reference, with an internal 1.4µA pull-up current from INTVCC. |
| 12 | RUN | input | Regulator enable pin where a voltage above 1.25V enables operation and a voltage below 1V places the part in shutdown, and it must not be left floating. |
| 13 | VIN | power_in | Main power supply input pin, operating from 4V to 15V, that should be closely decoupled to PGND with a low ESR capacitor of 10µF or more. |
| 14 | VIN | power_in | Main power supply input pin, operating from 4V to 15V, that should be closely decoupled to PGND with a low ESR capacitor of 10µF or more. |
| 15 | MODE/SYNC | input | Mode selection and external synchronization input that forces forced continuous operation when tied to ground and enables Burst Mode operation when floated or tied to INTVCC. |
| 16 | PGOOD | output | Open-drain power good output that is pulled to ground when the FB voltage is not within 8% (typical) of the internal 0.6V reference. |
| 17 | SGND | power_in | Signal ground exposed pad that must be soldered to the PCB for good thermal and electrical contact, with the feedback network, compensation network and RT resistor connected to this ground. |
