Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switch node output connected to the SW side of the external inductor, with normal voltage swing from ground to PVIN. |
| 2 | SW | output | Switch node output connected to the SW side of the external inductor, with normal voltage swing from ground to PVIN. |
| 3 | PGND | power_in | Power ground; the (-) terminals of the input capacitor CIN and output capacitor COUT must be tied to it with a low-impedance connection. |
| 4 | PGND | power_in | Power ground; the (-) terminals of the input capacitor CIN and output capacitor COUT must be tied to it with a low-impedance connection. |
| 5 | BOOST | power_out | Boosted floating driver supply; the bootstrap capacitor (+) connects here and (-) to SW, with swing from a diode drop below INTVCC up to PVIN + INTVCC. |
| 6 | INTVCC | power_out | Internal 3.3V regulator output that must 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; connect to the regulated output, with a normal pin impedance of 180kΩ. |
| 8 | RT | input | Oscillator frequency program pin; a resistor between 80k and 400k to SGND sets 800kHz to 4MHz, and tying it to INTVCC defaults the frequency to 2MHz. |
| 9 | FB | input | Output voltage feedback input to the error amplifier, which compares it to the internal 0.6V reference through an external resistor divider. |
| 10 | ITH | passive | Error amplifier output and compensation pin for the regulator loop; connect to INTVCC to use the default internal compensation. |
| 11 | TRACK/SS | input | Output tracking and soft-start input; forcing below 0.6V overrides the internal reference, and an internal 1.4µA pull-up lets an external capacitor to ground set soft-start. |
| 12 | RUN | input | Regulator enable pin; a voltage above 1.25V enables the chip, below 1V shuts it down, and it must not be left floating. |
| 13 | VIN | power_in | Main power supply input that should be closely decoupled to PGND with a low-ESR capacitor of 10µF or more. |
| 14 | VIN | power_in | Main power supply input 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; tying to ground forces forced continuous operation, while floating or tying to INTVCC enables Burst Mode operation, and an external clock synchronizes the oscillator. |
| 16 | PGOOD | output | Open-drain power good output that is pulled to ground when FB is outside ±8% (typical) of the 0.6V reference and goes high impedance once FB is within ±5% (typical). |
| 17 | SGND | power_in | Signal ground exposed pad that must be soldered to the PCB for thermal contact in the MSE package and serves as the return for the feedback network, compensation network and RT resistor. |
